Soft magnetic properties of FeCoSiAlGaPCB amorphous alloys

Substitution of Fe by Co in FeCoAlGaPCBSi amorphous alloys does not improve the glass-forming ability and decrease the Curie temperature, the saturation magnetization and the magnetostriction, the last reaching a nearly zero value. Structural relaxation of the samples is evidenced by an increase in the Curie temperature and a decrease of the coercive field.
