摘要：

Mossbauer spectra of Sm2Fe17Cy and Sm2Fe15Si2Cy as well as their parents, Sm2Fe17 and Sm2Fe15Si2, respectively, have been studied. Because of the influence of the C and Si atoms, at least five and seven subspectra are necessary to obtain a good fit to the data for Sm2Fe17Cy and Sm2Fe15Si2Cy, respectively. The effects of the C atoms on the hyperfine parameters are discussed. The hyperfine fields for the carbides increase on the 6c and 9d sites but decrease on the 18f and 18h sites as compared to those for their parents. This suggests an origin for the lower magnetization observed for Sm2Fe15Si2Cy as compared with that for Sm2Fe15Si2.
