Abstract：
Nitrogenation is an indispensable process for the formation of Sm2Fe17N3 and has a major influence on its magnetic properties. In this work, the effect of nitrogenation on the magnetic properties of Sm2Fe17N3 was investigated by micromagnetic simulation. The normal coercivity, remanence, and the maximum energy product of incompletely nitrided Sm2Fe17N3 with a nonnitrided Sm2Fe17 core size less than 16 nm approach nearly 99% of their values in fully nitrided Sm2Fe17N3. Thus, a small nonnitrided Sm2Fe17 core does not affect the effective utilization of Sm2Fe17N3 permanent magnets. The magnetization reversal mode of incompletely nitrided Sm2Fe17N3 with different sizes of nonnitrided Sm2Fe17 cores was evaluated, providing an in-depth fundamental understanding of the demagnetization processes in Sm2Fe17N3 particles. This work could be useful for optimizing nitrogenation conditions to improve the magnetic properties of Sm2Fe17N3 permanent magnets.
