Abstract

Annealing temperature dependence of the stress-induced magnetic anisotropy in Co 73Mo 2Si 15B 10 (λ s < 0) and (Co 0.89Fe 0.11) 72Mo 3Si 15B 10 (λ > 0) metallic glass ribbons has been studied experimentally. The room temperature values of the induced anisotropy constants K depend strongly on the annealing conditions, and reveal a change of sign at annealing temperatures well below T cryst. It is concluded that transient creep and steady-state creep at the elevated temperature give rise to compressive and tensile stresses, respectively, in the expression for the magnetoelastic coupling energy at room temperature.
