Influence of direct current on the hysteresis loops of Fe-based twisted amorphous ribbons

Abstract

The effects of longitudinal direct currents on the magnetization processes of Fe-based amorphous ribbons with a positive magnetostriction constant have been investigated by means of vibrating sample magnetometer. When the twisted samples are exposed to direct current, considerable changes in their hysteresis loops occur. The correlation between the changes of the hysteresis loops and the influence of direct current was explored both experimentally and by developing a simple realistic model.
