Abstract

Different techniques for reducing magnetic losses of grain-oriented silicon steel by laser irradiation have been examined. The explanation for the effects is given. The significant decrease in magnetic losses was found after a local laser treatment of an ultrathin strip of fine- grained anisotropic electrical steel. Magnetic loss in amorphous ribbons was found to be essentially reduced to 30% by local laser treatment in a wide range of magnetizing reversal frequencies. A special laser system for realization of local irradiation techniques is considered.
