The structure influence of carbon atoms in RFe10.5Mo1.5Cx (R = Nd, Y, Dy) compounds was investigated by using X-ray diffraction. A detailed 57Fe Mössbauer spectroscopy under 77 K and hyperfine field interaction are presented. The studies indicate that the incorporation of carbon atoms into its parent compound can increase the hyperfine field and the saturation magnetization. The result confirmed that the magnetic properties of RFe10.5Mo1.5 compounds can be improved by interstitial carbon atoms just like the influence of nitrogen atoms.
