Abstract
A simple model for the explanation of the decrease of coercive field Hc and loss E in magnetic ribbons carrying an electric current has been proposed. For lower currents accurate measurements performed on amorphous Co70.3Fe4.7B10Si15 ribbon confirm the validity of the model. The results for higher currents can also be explained in terms of the same model providing that the influence of the perpendicular field (caused by the current flow) on the actual domain structure is taken into account. Based on the model predictions a new type of soft magnetic material is proposed.
