Nickel-Zinc-Indium Ferrite: Magnetic Properties and Mossbauer Spectroscopy Characterization.

Nano nickel-zinc-indium ferrite (NZIFO) (Ni0.58Zn0.42InxFe2-xO4) particles with varied quantities of indium (x = 0, 0.1, 0.2) have been chemically synthesized through a reverse micelle reaction and investigated by X-ray diffraction, transmission electron microscopy and by magnetic and Mossbauer spectral studies. The dependence of Mossbauer parameters, viz, isomer shift, quadrupole splitting, linewidth and hyperfine magnetic field on In3+ concentration have been discussed. Mossbauer results are also supported by magnetization data. With these interesting ferromagnetic properties indium substituted nano nickel-zinc ferrites have potential applications in magnetic storage data. The dependence of Mossbauer parameters on nano NZIFO particles at 5 K and 300 K has been studied. The values of Bloch exponent (α) are in well accordance with that reported for bulk materials.
