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.
