The effect of entering of Fe-atoms and Sn-atoms into crystal lattice of permanent magnet SmCo5 on the X-ray diffraction relative intensities is studied. It is observed that the Fe-atoms can replace the Co-atoms on any site, but they replace Co2c more readily.However, the Sn-atoms replace the Co-atoms or 3 g sites more easily. The replacement of Co-atoms by the Sn-atoms can increases the ratio of X-ray diffraction relative intensity I200/I111, but the striking changes of this ratio is largely due to the alignment, the order of Fe, Sn atoms, the improvement of internal stress conditions, and the controlling of the 750℃ phase transformation.
