Magnetic Relaxation in Amorphous (Fe1-xNix)77Si10B13 Alloys

Abstract
Disaccommodation (D A) and the magnetic annealing effect in amorphous (Fe1-x Ni x )77Si10B13, 0≦x≦0.8, alloys have been studied as a means of investigating the mechanism of structural relaxation in amorphous solids. The relaxation process is divided into two stages. The first stage, bolow about 200°C, is caused by the movement of metalloid atoms and the second, above 200°C, by diffusion of the constituent atoms. It is shown that the origin of D A is the same as that of induced magnetic anisotropy.
