Abstract

The dynamics of the magnetization reversal by means of head-to-head domain-wall propagation is investigated both experimentally and theoretically for magnetic labels made from Fe-rich bistable glass-coated microwires. It is shown that the amplitudes of the electromagnetic harmonics generated by bistable Fe-rich magnetic labels of the length 1―4 cm with metallic nuclear diameter of 10―20 μm are more than 5 times larger than that of similar labels made of Co-rich microwires having high permeability and low coercive force. The electromagnetic harmonics can be detected at the distances up to 15― 20cm from the magnetic label at the signal-to-noise ratio not lower than 2.0.
