采用放电等离子烧结（SPS）方法将Sm-Fe-N粉末烧结成块体材料。虽然在磁体中观察到Sm 2Fe 17 N3相的部分分解，但是通过向Sm-Fe-N粉末中添加少量Zn粉末来减少分解。由Sm-Fe-N和Zn粉末的混合物获得的各向异性Sm-Fe-N磁体表现出0.90T的高剩磁和0.54MAm-1的矫顽力。
Sm–Fe–N powders were consolidated into bulk materials by the spark plasma sintering (SPS) method. Although partial decomposition of the Sm2Fe17N3phase was noted in the magnets, the decomposition was reduced by the addition of a small amount of Zn powder to the Sm–Fe–N powder. The anisotropic Sm–Fe–N magnet obtained from a mixture of Sm–Fe–N and Zn powders exhibited a high remanence of 0.90T with a coercivity of 0.54MAm−1.
