A new mechanism for magnetic annealing in amorphous metals

Magnetic annealing effects in amorphous alloys can be accounted for by the selective replacement of single atoms in the DRPHS structure, in such a way as to bias the initially random distribution of atomic local anisotropies. The composition dependence predicted by this model agrees well with results on Fe-Ni-B and Fe-Ni-P-B amorphous alloys without modification for tendencies toward clustering or compound formation. The model accounts for magnetic annealing effects in Fe-only alloys.
