title = "Magnetic field-induced nitridation of Sm2Fe17",
abstract = "Nitridation of Sm2Fe17 powder was performed under a 5-T magnetic field for the temperature range 623–743 K to clarify the magnetic field effect on nitridation. Applying a magnetic field of 5 T promoted nitridation by approximately 0.6 nitrogen atoms per formula unit compared with zero-field nitrogenation, and almost fully-nitride Sm2Fe17N2.9 was obtained at 743 K. The magnetic field effect was discussed using a grain growth model based on magnetic properties of nitride-poor Sm2Fe17Nx (x < 3) phase and fully-nitride Sm2Fe17N3 phase. The obtained results show that in-field nitridation helps to synthesize nitride Sm2Fe17N3 system in the present condition.",
