We report the displaced hysteresis loops in the annealed amorphous alloys F
e65.9Cr11.6Si7.5B15 and Fe60Co5.9Cr11.6Si7.5B15. The effects of measuring f
ield H-m, temperature T and time t on the displacement H-D have been studie
d. On the basis of the magnetostatic interaction between the hard particle
resulting from the annealing and the residual amorphous soft matrix, the ex
periments could be well explained by the unidirectional anisotropy model.
