SOFT MAGNETIC MATERIAL AND METHOD FOR PRODUCING SAME

摘要

A soft magnetic material according to the present disclosure contains particles, each of which comprises a plurality of nano-sized crystallites and an amorphous phase that is present around the crystallites, and wherein: the average particle diameter of the crystallites is 30 nm or less; the average thickness of the amorphous phase is 30 nm or less; and if the breadth of a cross-section of each particle is r, the average Fe concentration in the amorphous phase is lower than the average Fe concentration of the crystallites in a region ranging from the depth of 0.2r (inclusive) from the surface of the particle to the depth of 0.4r (inclusive) from the surface of the particle.
