Abstract

The effect of creep annealing on the57Fe enriched Co-rich low magnetostriction amorphous alloys will be reported. Contrary to the Fe-B-base alloys, after creep annealing of the57Fe5Co57Ni10Si11B17 the ribbon axis becomes the hard direction. Both Mössbauer spectroscopy and direct magnetic domain observations by SEM confirmed an enhanced volume with magnetization oriented in transversal and normal directions to the ribbon axis. Relaxation of the creep-induced state at a temperature slightly below that of the creep annealing leads to the enhancement of the fraction of domains magnetized in the longitudinal direction.
