Abstrakt: The contribution of anisotropic hopping to magnetostriction is calculated for a CoNiSiB amorphous sample. The calculations are performed for both as-quenched and annealed samples. Partial directional ordering of 3d atom pairs makes magnetostriction about twice smaller after the annealing, as was observed in experiment. Two-ion magnetic interaction in amorphous alloys is concluded to be responsible for annealing-induced changes of the magnetostriction λS.
