Simultaneous observation of viscoelastic deformation and induced magnetic anisotropy in [Co1−x(FeNi)x]75Si15B10 metallic glasses

Abstract
Amorphous ribbons of composition [Co1−x(FeNi)x]75Si15B10 (0.1<x7 A m2 have been used. Viscoelastic deformation and induced magnetic anisotropy were determined simultaneously after the treatments at room temperature. The induced anisotropy consists of two contributions, one irreversible and the other recoverable. The strength of the anisotropy and the deformation depends on the anneal temperature, the thermal history of the sample and the composition. The composition dependence of the plastic deformation and the induced anisotropy is similar and the influence of preannealing on magnetic anisotropy and linear deformation is considerable.
