Correlation between saturation magnetization, magnetostriction and creep-induced anisotropy in amorphous (FeCo)/sub 85/B/sub 15/ alloys

Compositional dependence of saturation magnetization, magnetostriction and creep-induced magnetic anisotropy is investigated in amorphous (Fe/sub 1-x/Co/sub x/)/sub 85/B/sub 15/ alloys. A close correlation of the three quantities was found. An anomaly centred at x=0.25 may indicate chemical short-range order of the Fe/sub 3/Co type in this concentration range. An explanation of the creep-induced anisotropy behaviour based on the bond-orientational anisotropy model is presented. It takes into account both the short-range ordering in the shear centres and medium-range deformations of their surroundings.<
