Induced magnetic anisotropy of Co‐based amorphous alloys

摘要

The effect of the rotating magnetic field annealing on high magnetic induction amorphous alloy Fe5Co75Si4B16 (TC≳Tx) was studied. Experimental results and the theoretical analysis gave the following conclusions. 1) Induced magnetic anisotropy is dispersed by the rotating magnetic field annealing. 2) The relationship between magnetic permeability μ and number of rotations R is given by the formula 3) The rotating field annealing is useful to eliminate the induced magnetic anisotropy, especially for the amorphous materials with TC≳Tx.
