Studies of the remagnetization process in cold drawn Fe-rich thin amorphous wires

Results on local hysteresis loops for Fe-rich amorphous cold-drawn wires with the sample lengths of 30 mm and 70 mm under applied stress, sigma, up to 1300 MPa are reported. For both lengths, the magnetization, M, increases with s and the coercive field, H-C, decreases. Near the wire end, M results to be larger than at the wire center, and HC sharply decreases. This reduction is eliminated if the applied stress is large enough. It is assumed, that the magnetic configuration at the wire end for the cold-drawn wires is different from the other wires families.
