The changes in phase structure and Curie temperature of the Sm2Fe17 compound after nitrogen absorption were studied by using X-ray diffraction, differential thermal/thermo-gravimetric analyzer and magnetic measurement. The results of X-ray diffraction showed that the diffraction peaks of the Sm2Fe17 compound shifted toward lower angle after nitrogen absorption, and the characteristic peaks of α-Fe were observed. This showed that the unit cell of Sm2Fe17 expanded, the compound was decomposed to a certain extent and the characteristic peaks of α-Fe appeared.

通过X-射线衍射、差热－热重联用仪以及磁测量等手段，研究了Sm2Fe17化合物吸氮后的相结构及居里温度的变化行为。X-射线衍射表明，吸氮后Sm2Fe17化合物的衍射峰向小角度方向偏移，并且出现了α-Fe的衍射峰，这说明吸氮后化合物的晶胞有所膨胀，并且化合物有一定的分解，产生了α-Fe。
