Abstract
Effect of tensile stress on the magnetization properties of silicon steel sheet samples declined from rolling direction was investigated. Magnetization for B8 showed minimum value at the angle of 55°, which is <111> direction. Reversible and irreversible magnetization change due to tensile stress was also measured for samples at various angles from rolling direction. The reversible magnetization change due to angle shows no differences among samples at low magnetic field. The differences only appear at high field. The reversible magnetization change shows peak value at the angle of 55°, which corresponds to the minimum value of magnetization for B8. The differential magnetization change with respect to tension, which indicates the ease of movement of domain wall, shows almost similar characteristics with the reversible magnetization change. The domain structure for the sample changes drastically due to tension when the angle is increased beyond 60°.
