Abstract
The longitudinal and transverse magnetoresistances in amorphous Fe77.5Si7.5 B15 wires are studied at different values of the DC-bias currents in order to clarify the mechanism of the magnetization according to a 'core-shell' d omain model. The role of closure domain structures in the magnetization pro cess of the wires is analysed. Moreover, the effects of the Joule heating o n the internal stresses, introduced during the rapid quenching in the sampl e preparation, are examined. (C) 2001 Published by Elsevier Science B.V.
