Influence of the Circular Magnetic Field and the External Stress on the Remagnetization Process in Fe-Rich Amorphous Wires

The remagnetization process of Fe-rich wires as dependent on the circular magnetic field induced by the AC current flowing through the wire is investigated experimentally. We present the dependence of the switching field on the amplitude and frequency of the circular magnetic field and its variance with the applied tensile stress. The results are interpreted in terms of magnetic domain structure of the wire.
