Abstract or Description

The temperature stability of field induced uniaxial anisotropy(KU) was investigated by thermomagnetic treatments of (Co1−xFex)89Zr7B4amorphous ribbons after field annealing below and above the crystallization temperature. We conclude: (1) Field annealing treatments are necessary to properly investigate the temperature stability of KU, (2) KU of field crystallized alloys exhibit improved temperature stability relative to alloys remaining amorphous after field annealing, and (3) larger KU is obtained for field crystallization treatments as compared to zero-field crystallization followed by field reannealing. Field crystallization may be required for elevated temperature applications when field induced anisotropy is critical for performance.
