Abstract

The asymmetric giant magnetoimpedance (GMI) curve has been measured under the rotating field as a function of temperature in Co-based amorphous ribbon. The magnetic softness in the amorphous phase is enhanced at temperature between 370 and 415 K. The bias-field caused by the hard magnetic phase is nearly constant up to 350 K and then rapidly decreases with temperature. The field angle of 95° from the ribbon axis for maximum impedance increases to 97° at a temperature of 440 K, indicating a little change of anisotropy configurations with temperature.
