Stability of the amorphous magnetic state against asymmetric magnetization reversal

Abstract

Magnetic instability during asymmetric magnetization reversal in crystalline materials was first investigated systematically by Néel who interpreted it as a superposition of the reptation (=accomodation) and bascule effects. We found similar effects in the amorphous Fe-B alloy but the changes of magnetic polarization were smaller than in the crystallized state, and there was a bigger stability region inside the hysteresis loop. The dependence on the number of magnetization reversals in the amorphous and appropriate crystalline materials is also different.
