Recent Research on the Magnetoimpedance Effect in Co-Based Amorphous Ribbons

Abstract:

We report the recent results obtained on the magnetoimpedance (MI) response in several near-zero magnetostriction Co-based amorphous ribbons with different width, and different transverse magnetic anisotropy (developed during the fabrication process or processing after production by the current annealing technique) in the frequency range of 10 MHz – 3.5 GHz. The evolution of the maximum of MI with the axial magnetic field, ascribed to the anisotropy field, as a function of the frequency provides useful information on the soft magnetic character of the ribbons.
