Abstract
The stress anneal induced anisotropy has been studied in metallic glass ribbons of the compositions (Co 1- x Fe x ) 75Si 15B 10, 0≤ x≤0.12. The induced anisotropies are found to consist of two contributions, an irreversable one and a recoverable one. From their thermal variations and from their stress dependence the anisotropy constants have tentatively been related to the constituents of the saturation magnetostriction coefficients. The kinetics reveal for the recoverable anisotropy a continuous spectrum of activation energies in the range 1.55–1.8 eV.
