The Sm 2 Fe 17 N 3 phase decomposes into SmN and α-Fe phases once the ambient temperature exceeds 650 degrees Celsius. SmFeN magnets were first commercialized by Japanese companies in the field of bonded magnets. The isotropic magnets or anisotropic magnets require a stable raw material SmFeN powder. Both Nichia and Sumitomo used reduction diffusion to obtain anisotropic powders that are well suited for injection molding magnets.
