中文摘要Fe-57 Mossbauer spectra of Sm2Fe14Ga3Cx (x=0, 0.5, 1.0, 1.5, 2.0, 2.5) collected at 293 K have been analysed using a simplified fitting model of four (for x=0) or six (for x not equal 0) broadened sextets which ignores the local Ga environment of each Fe site. Our analyses show that the strong Ga preferential occupation of 18h site model results in the best fit to the experimental spectrum. The values of the hyperfine field of four sextets with zero neighbouring carbon are virtually constant for all x, namely, 28.7(5), 22.9(5), 20.8(5) and 20.3(5) T. The reduction in hyperfine field with one neighbouring carbon for 18f site is 6.3+/-0.8 T; whereas for 18h site it is only 2.7+/-0.1 T. The average hyperfine field decreases slightly with the carbon content, which suggests that the average Fe magnetic moment is largely unaffected by the introduction of carbon. Using a conversion factor of 15 T/mu(B), the average Fe atomic magnetic moment in Sm2Fe14Ga3 is about 1.47 mu(B) at 293 K. The volume expansion resulting from the introduction of carbon leads to a slight increase in the weighted average of the Fe-57 isomer shift.
