Abstract

Amorphous Fe40Ni40B20, (Co95Fe5)75Si15B10(Co88Fe12)75Si15B10, and (Co89Fe11)72Mo3Si15B10ribbons have been annealed by means of short current pulses while a tensile stress was simultaneously applied. The temperature of the ribbons was determined by magnetic measurements and by using a thermocouple attached to the samples. In the temperatures between 300 and 500°C a perpendicular magnetic anisotropy is induced in the Co-rich glasses. The magnitude of this anisotropy varies with the annealing temperature and the thermal history of the sample. Changes in the saturation magnetostriction have been found in the (Co95Fe5)75Si15B10alloy. The results are in overall agreement with those obtained by conventional annealing under stress.
