Abstract
The dependence of the magnetic parameters as switching field H*, coercive fieldH c and reduced remanencem r , on applied tensile stress σ a has been studied in current annealedamorphous wires. The switching field increases as σ 1/2 a in fully relaxed samples, while in both ‘‘as‐quenched’’ and partially relaxed samples the σ 1/2 a law holds only at high values of σ a . The coercive field increases with σ a in a way similar to H* and m r increases up to the saturation value. This behavior can be explained by taking into account the different magnetic regions that have been proposed for these wires.
