Ambient Magnetic Field Effect on Stress-Magnetization Changes of Co-based Amorphous Ribbons due to Heat Treatment

摘要

Stress-magnetization properties of Co-based amorphous ribbon were investigated. The sample was heat treated with longitudinal magnetic field. Unique magnetization changes due to stress application were observed, when ambient magnetic field was applied during the stress-magnetization measurement apart from an exciting magnetic field. The unique stress-magnetization changes were, however, not observed at high exciting magnetic field though ambient magnetic field was applied.
