Abstract

We have measured the variation of magnetoimpedance (MI) ratio on Fe_71+xNb₇B_22-x (x = 0, 2, 6, 8) amorphous ribbons for the evaluation of anisotropy field H_k. MI at a frequency of 10 MHz is related to the transverse permeability from rotational magnetization. MI varies sensitively with the various Fe-contents, reflecting the magnetic softness. The field interval of the MI peaks corresponds to the anisotropy field (H_k) and the estimated H_k decreases with the Fe-contents.
