Abstract

The influence of direct (J_d) and alternating (J_a) core-currents on the magnetization has been considered. A simple model of a ribbon consisting of two domains separated with π-domain wall is used in order to explain the effects of core-currents on the M-H loop. The variations of the coercive field H, with the field Hp induced by J_d and J_a have been calculated The achievement of H_c=0 at sufficiently large Hp is predicted both for J_d and J_a. The experiments performed on amorphous Co_70.3Fe_4.7Si₁₅B₁₀ ribbon yield H_c=0 for sufficiently large J_a but not for J _d. This discrepancy for J_d can be explained in terms of the more complex domain structure of the actual ribbon
