ABSTRACT:
In a method of producing a grain-oriented electromagnetic steel sheet, a laser beam is irradiated onto the steel sheet, which has been subjected to a final high temperature annealing in order to approximate the crystal orientation of the sheet in a (110), [001] orientation. Because of the laser beam irradiation, regions of high dislocation density are locally formed in the steel sheet and subdivide the magnetic domains, with the result that a low watt loss is achieved.
