Abstract:
Provided is a method for manufacturing magnetic particles, in which an oxidation treatment, a reduction treatment, and a nitriding treatment are performed in that order on raw material particles with a core-shell structure in which a silicon oxide layer is formed on the surfaces of iron microparticles, thereby nitriding the iron microparticles while maintaining the core-shell structure. Due to this configuration, granular magnetic particles with a core-shell structure in which a silicon oxide layer is formed on the surfaces of iron nitride microparticles can be obtained.

Claim (Index 1):
Magnetic particles being spherical particles each having a core-shell structure in which a silicon oxide layer is formed on a surface of an iron nitride fine particle, wherein the iron nitride fine particle is composed of Fe 16 N 2 .
