摘要： PROBLEM TO BE SOLVED: To improve the iron loss with a magnetic domain subdividing effect of the combination of a closure magnetic domain and a strain distribution and to reduce the magnetostriction by applying the magnetic domain control with the irradiation of laser beam on the surface of silicon steel sheet and forming a specific closure magnetic domain and the strain in a specific sheet thickness direction on this irradiated surface. SOLUTION: The laser beam irradiates the surface of the grain oriented silicon steel sheet to introduce the strain and execute the magnetic domain control. At this time, the irradiating laser beam width and the introducing energy are adjusted to form the width orthogonally crossing to the irradiating direction of closure magnetic domain developed on the irradiated surface to =30 μm. It is desirable that the irradiating traces are overlapped with the laser beam as a pulse type and this laser beam irradiates into the direction of 60-120 deg. to the rolling direction of the steel sheet. Further, the spot of this laser beam is formed as elliptical shape having the major axis in the irradiating direction, and the width in the rolling direction orthogonally crossing to the irradiating direction is desirable to be made small.
