Abstract
A method of manufacturing a magnetic material, includes a surface oxides decreasing step of decreasing surface oxides of an iron powder; a powder-molded body forming step of mixing the iron powder whose surface oxides are already decreased obtained by the surface oxides decreasing step, and a compound powder 'A' constituted by a La element and a Si element, and compressing and molding the obtained mixture powder; and a sintered body forming step of preparing a sintered body from the powder-molded body obtained by the powder-molded body forming step, by a solid phase reaction under vacuum atmosphere.
