Abstract

The resonant magnetoelectric (ME) effect of Fe78Si9B13/Pb(Zr,Ti)O3 (FeSiB/PZT) composites with a surface-modified Fe78Si9B13 amorphous alloy has been studied. The surface-modified FeSiB can improve the ME coefficient at the resonant frequency by optimizing the magnetomechancial power conversion efficiency. The maximum ME coefficient of the surface-modified ribbons combined with soft PZT (PZT5) is two-thirds larger than that of the composites with fully amorphous ribbons. Meanwhile, the maximum value of the ME coefficient with surface-modified FeSiB ribbons and hard PZT (PZT8) is one-third higher compared with the fully amorphous composites. In addition, experimental results of magnetomechanical coupling properties of FeSiB/PZT composites with or without piezoelectric layers indicate that the power efficiency of the composites first decreases and then increases with the increase in the number of FeSiB layers. When the surface crystalline FeSiB ribbons are combined with a commercially available hard piezoelectric ceramic plate, the maximum magnetoelectric coupling coefficient of the ME composite reaches 5522 V/(Oe*cm), of which the electromechanical resonant frequency is 23.89 kHz.

Abstract

Fe-based amorphous alloys have advantages of low iron loss and high effective permeability, which are widely used in sensors and actuators. Power efficiency is one of the most important indicators among power conversion applications. We compared the magnetomechancial power conversion factors of metallic glassy ribbons FeCoSiB (Vitrovac 7600) and FeSiB (Metglas 2605SA1). We investigated the crystallization process under different annealing temperatures and tested the magnetomechancial coupling factors (k) and quality factors (Q) by using resonant and anti-resonant methods. We found that the maximum coupling factor of the annealed Vitrovac ribbons was 23% and the figure of merits k2Q was 4–7; however, the maximum coupling factor of the annealed Metglas ribbons was 73% and the maximum value of k2Q was 16. We can observe that the Metglas 2605SA1 ribbons have higher values of the magnetomechanical power efficiency than those of the Vitrovac 7600 ribbons, which means they are better to be used in subsequent research regarding acoustically driven antennas.

Abstract

In this paper, we propose a general model to evaluate the equivalent magnetic noise for an off-diagonal giant magneto-impedance (GMI) sensor utilizing a software-defined radio (SDR) as a digital receiver. Based on this SDR approach, an analog-to-digital conversion (ADC) of the voltage induced by the sensing element is directly performed. The signal processing is digitally achieved in real time. It includes a digital quadrature demodulation, a decimation, and a filtering. The approach allows to give the key rules for quantifying the white noise level of this digital implementation. The voltage noise spectral density of the ADC and of each SDR stage is given. The white noise level expected by the modeling was in good agreement with the measurements. With a sensing element composed of a 400 turn coil wound around a co-rich GMI wire, equivalent magnetic noise levels of 220 and 4.2 pT/ $\sqrt {Hz}$ were obtained at 1 Hz and in the white noise region, respectively. The potential improvement of these performances, allowed by this digital conditioning, as well as limitations is also discussed.

Abstract

The detection limit of thin film giant magneto-impedance (GMI) magnetic sensors has been investigated by measuring their magnetic noise. The GMI sensing elements are multilayers based on Fe20Ni80 Permalloy (Py), deposited by sputtering and patterned by photolithography in the form of 2-mm long and 50- to 130- $\mu \text{m}$ wide stripes. The multilayered samples had the following structure: [Py(170 nm)/Ti(6 nm)]3/Cu(250 nm)/[Ti(6 nm)/Py(170 nm)]3. As electronic conditioning circuits, different configurations of oscillators and detectors were tested in order to determine their influence on the total output voltage sensor noise. The latter was measured using a dynamic signal analyzer and the equivalent magnetic noise of the sensor was determined through the measured Fourier transfer function of the device at the operating point. Filtering and impedance matching strategies were implemented to minimize the equivalent magnetic sensor noise. Presently, a white noise level of 120 pT/ $\surd $ Hz at 2 kHz is obtained.

Abstract

Magnetostrictive-piezoelectric composite in bi-layer structure shows a resonant enhancement for the mechanical strain mediated magnetoelectric coupling when operating under bending mode. Such composite is of importance to achieve ultrasensitive magnetometers for detecting quasi-static magnetic fields by measuring the parameter variation near the resonant frequency. Detection performance is limited by diverse noise processes appearing in the composite and associated electronics such as the extrinsic interferences due to the environmental vibration and temperature and loss noise sources produced by the energy dissipation in the composite. Since the bending resonance is based on the mechanical interactions in the composite, the noise source due to the thermo-mechanical dissipation becomes an importance noise process to be investigated. In this paper, we investigate the field detection performance relating to the thermo-mechanical and thermo-electric dissipation in a doubly clamped magnetoelectric composite by means of modulation techniques.

Abstract

International audience; The equivalent magnetic noise of the magnetoelectric (ME) layered composite sensors has been investigated for various modulation techniques. The ME thin film response to an electric modulation or a magnetic modulation can be sensed by using either a charge amplifier or a coil wound around the sample and then demodulated by a synchronous detector. The equivalent magnetic noise for these excitations methods has been compared. As expected, the low-frequency fluctuations can be lowered when the magnetoelectric sensor is operated in a modulation mode. Results show that these methods can give the same level of equivalent magnetic noise for a certain strain-excitation. In theory, mechanical noise appears as the only dominant noise source after the demodulation process in the case of a certain strong amplitude excitation carrier signal. By using these modulation techniques, an equivalent magnetic noise level of 10-100 pT/Hz at 1 Hz was achieved with DC capability.

Abstract

International audience; GMI-based magnetometers offer a competitive alternative to well-established fluxgate magnetometers for relatively low-cost and highly-sensitive magnetometers [1]. While state-of-the-art GMI magnetometers can operate at much higher frequency than fluxgates and exhibit sub-pT/Hz1/2 equivalent magnetic noise, somewhere between 100 Hz and 1 kHz and above, they are, however, plagued by 1/f-noise, degrading their performance at low frequencies. We have recently shown that part of this noise was intrinsic to the GMI sensing elements [2]. Since 1/f noise can be associated with time-dependent fluctuators, such as magnetic fluctuations [3] or electronic noise at an electrical junction, we have speculated that it may originate either from poor electrical contacts or from closure magnetic domains at the GMI microwires extremities. We have thus conducted a study of the effect of various physico-chemical treatments on the GMI performance of CoFeSiBNb GMI wires, whose objective is the establishment of a systematic procedure for wire preparation, yielding wires with reproducible and improved GMI performance.A series of nominally identical microwire segments, with no apparent defects based on optical microscopic observations, were current-annealed under tensile stress. The wires were then divided into different groups, each submitted to a distinct combination of treatments, such as acid etching or laser melting to smooth out the wire extremities, or Cu electroplating to improve the electrical contacts. Characterization of the GMI sensitivity at 10 MHz and of the magnetic noise spectra over a broad frequency range is being carried out on all samples. The effect of each treatment is assessed by comparison of each wire group with the control group, which was not submitted to any treatments, and with complementary characterization by VSM magnetometry and by FMR spectroscopy. The results are compared with predictions for the behavior of uniform cylindrical wires and the noise model developed in Reference [3]. -----------------------------------------------------------References[1] B.

Abstract

We report a magnetoelastic effect in doubly clamped ferromagnetic magnetostrictive Metglas resonators with electrically and magnetically reconfigurable frequency response. The field-induced resonance frequency shift is due to magnetostrictive strain, which is shown to have a strong dependence on uniaxial stress. Here, we demonstrate that this magnetic field induced behavior can be used as the basis for a simple, tunable, magnetoelectric magnetic field sensor. The effect of tension on the field dependent magnetostrictive constant and the sensor sensitivity is examined, and the equivalent magnetic noise floor of such a sensor is estimated.

Abstract

International audience; An optimized giant magneto-impedance effect magnetometer has been developed, based upon an overall analysis of the measurement chain, including physical material properties, associated detection coil parameters, and equivalent magnetic noise performances. The field response model for the sensing element and the noise model yield good agreement with experimental results. The noise performance of the magnetometer, approximately 1.7 pT/ √Hz in the white noise region, with a band-pass of about 70 kHz, is competitive with that of other technologies. Present limitations are clearly established, leavingroom for further improvements.

Abstract

International audience; The performance of multi-segments magneto-electric (ME) layered sensors as charge sources has been investigated by using a typical charge amplifier. We found that the intrinsic performance of such sensors consisting of several (namely 3 and 5) segments, is the same whether these segments are connected in parallel or in series. Both, the signal detecting capacity and the intrinsic noise source of ME layered sensors depend on the volume of sensor. We have measured an equivalent magnetic noise of about 1 nT√Hz at 1 Hz and as low as 10 pT√Hz in the white noise region

Abstract

International audience; 1 INTRODUCTIONThe giant magnetoimpedance (GMI) effect has great potential for the design of highlysensitive magnetometers. It has previously been shown that the performance of GMImagnetometers is currently limited by the noise due to electronic conditioning [1, 2].Therefore, an increase of the intrinsic sensitivity of the sensing element is a key point in the reduction of the impact of electronic noise on global performance. A promising approach to reaching that goal is to use a coupled pick-up coil wound around the GMI element in a twoport configuration [3]. Here, we propose a model for the equivalent output magnetic noise of a complete electronic circuit of a magnetometer using the two-port configuration as the sensing element. This allows us to clarify the main contributions to sensor noise performance, operating at the optimal sensor excitation working point.------------------------------------------------2 NOISE MODELThe sensing element consists of a very thin two-layer pick-up coil wound on a 100μmdiameter CoFeSiB soft amorphous ferromagnetic wire. The response of the device tomagnetic field variation is fully described by its two-port network impedance matrix. Theintrinsic sensitivity of each matrix component is then deduced from the differentialimpedance variation as a function of applied magnetic field. First, we quantify thecontributions from all noise sources of the electronic chain. Then, we predict the outputsensitivity, in V/T, of each of the matrix components. Finally, the output noise level, inT/√Hz, the ratio of the output electronic noise to the output sensitivity, is calculated. Themodel is in good agreement with noise measurements in which the measured white noiseis at the pT/√Hz level. The two-port configuration, with the pick-up coil, clearly yields animprovement in noise performance, compared with the one-port measurement of theimpedance of the wire.--------------------------------REFERENCES:[1] L.G.C.

Abstract

International audience; The giant magnetoimpedance (GMI) effect is observed when the impedance of a magnetically soft conductor is measured as a function of frequency of the drive current and the applied external dc field. 1 Technological applications of the GMI effect such as magnetic, current and stress sensors 1 primarily require high impedance variation, high intrinsic sensitivity to dc and ac fields and low intrinsic magnetic noise. The magnitude of the effect, ΔZ, is commonly given by the change of impedance relative to the impedance at saturation. The sensitivity, S (in units of %/Oe or %/T), is proportional to the derivative of ΔZ with respect to the applied dc field. The magnetic noise, MN (in units of T/√Hz), which is a quantity proportional to the voltage-noise-to-sensitivity ratio, defines the minimum measurable field in 1Hz bandwidth and dictates sensor performance. In this work, the experimental and theoretical behaviour of S and MN are analyzed as a function of frequency and applied fields, including the effect of a dc bias current, for a Co-based magnetic conductor. A procedure to obtain the external parameters yielding the highest S and minimum MN is outlined. We have recently proposed a simple model to evaluate the GMI MN and S in the MHz regime of anisotropic magnetic wires. 2 The model accounts for a biasing dc circumferential field, H bias , which is included in the internal field of a single domain cylindrical magnetic conductor. For given frequency , H bias and easy axis direction, S is evaluated as a function of the external axial dc field, H ext. The field yielding the maximum sensitivity (S max), H ext max , is determined, defining the sensor working point. The MN is then evaluated at H ext max. For helical magnetic structures having the easy mag-netization axis close to circumferential, calculations show that both S max and MN (at H ext max) decrease for increasing H bias. 2 The field H bias essentially increases the internal field, which effectively makes the wire magnetically harder and hence, less sensitive to the driving signal when H ext is applied. Calculated normalized sensitivity, Λ, as a function of H ext and H bias at 10MHz for a 35μm diameter is presented in Fig. 1. The quantity Λ is given by Λ=H k S, where H k is the anisotropy field of the wire and S=dη/dH ext. η=(ξμ t 1/2-1)cos 2 θ, ξ is a function of the wave vectors and material parameters , 2 μ t is the transverse permeability and θ is the angle between the static magnetization direction and the direction of H ext. The permeability depends on frequency, internal field and magnetic damping. The parameter values used in the calculations are typical for Co-rich amorphous wires. Also, we have used H k =1.4Oe and an easy axis angle of 72 o (relative to the axial direction) in the calculations. We observe in Fig. 1 that for this frequency and easy axis angle, S broadens with S max (black points) decreasing when H bias is applied (see also broken lines A and B), as a consequence of the increase of the internal field. This may not be the case for a wire with an axial easy axis. Figure 2 shows experimental results of ΔZ/R dc and S from the measurement of the impedance of an as-cast Co-based wire as a function of H ext , when the wire was submitted to a dc bias current, i bias. The impedance was measured in a HP 8753B Network Analyzer (NA). For the i bias , injected into the device, we used the bias input of the NA. The experimental sensitivity shown in Fig. 2 was then obtained from the numerical derivative of the impedance versus field curve. In Fig. 2a, ΔZ/R dc and S vs. H ext at f=10MHz and 100MHz for i bias =20mA are shown. This value of i bias is equivalent to a H bias~2 Oe at the surface of the wire, which is close to the H k of this sample. Figure 2b shows S vs. H ext at f=100MHz for i bias =40mA, 20mA and 4mA. These results show that there are optimal frequency and dc bias conditions to maximize the sensitivity. The high S max for a non-zero H bias opens the possibility for the observation of very low values of MN predicted by the theory. 2 In this work, the behavior of S and MN are analysed and compared with experiment at frequencies up to 500MHz on Co-based amorphous wires.
