Document Type and Number:

WIPO Patent Application WO/2012/001957

Kind Code:

A1

Abstract:

The magnetic domain is segmented by exposure to a laser and an oriented magnetic steel sheet that meets recent demands for reduced iron loss can be obtained by limiting the amount of nitrogen (N) within a forsterite coating, on an oriented magnetic steel sheet with a magnetic field strength (B8) of 1.91 T or more, to 3.0 mass% or less.
