Abstract

The asymmetric giant magnetoimpedance curves have been measured under the rotation of magnetic field on the weak-field annealed Co-based amorphous ribbons to analyze the characteristics of bias field. The bias field from the hard magnetic phases is expected to be of an order of 100 Oe along the annealing field direction. The effective field of soft magnetic phase in the field region parallel to the bias field is less than that antiparallel to the bias field, indicating that an antiferromagnetic exchange coupling exists between the magnetization of the soft phase and the bias field of the hard magnetic phases.
