Structural relaxations in amorphous Co-Fe-Si-B alloys

The induced magnetic anisotropy, the saturation magnetostriction and the average hyperfine induction and its standard deviation at /sup 57/Fe nuclei for the pre-annealed samples of the amorphous Co/sub 78-x/Fe/sub x/Si/sub 11/B/sub 11/ (x=2, 4, 6 and 8 at.% Fe) alloys were measured after isothermal annealing. Changes of these magnetic quantities were attributed to reversible and irreversible structural relaxations. After each stage of interrupted isothermal annealing the linear dependence of the saturation magnetostriction on the composition was observed.<
