EFFECTS OF LONGITUDINAL CURRENTS AND TORSION ON THE MAGNETIZATION PROCESSES IN AMORPHOUS WIRES

We have studied the effects of longitudinal currents and torsion on the magnetization process of positive, negative and nearly-zero magnetostrictive Co-, and Fe-based amorphous wires. In the presence of a dc current flowing through the wire we observe a shift in the bi-stable magnetic response which is dependent on the sign of the magnetostriction. The well known bistable magnetic switching character is also observed in our Inverse-Wiedmann-Effect, IWE, studies of these wires. The importance of the sign of the magnetostriction on the observed IWE-response studies are also presented. © 1990 IEEE
