RFe10.5Mo1.5Cx (R=Y, Nd, and Dy; x=0-0.6) have been successfully synthesized by arc melting, then followed by a gas-solid phase reaction to form YFe10.5Mo1.5CxN y. X-ray diffraction studies and thermomagnetic analysis show that all samples are of good single phase, and carbides and carbon nitrides remain the ThMn12-type structure. The addition of carbon atoms has an effect of improving the magnetic properties. Both Curie temperature and saturation magnetization are found to be increased with carbon concentration x in the RFe10.5Mo1.5Cx series, and the carbon atoms also affect the magnetocrystalline anisotropy. The easy axial anisotropy of NdFe10.5Mo1.5Cx and DyFe10.5Mo 1.5Cx is enhanced. As to the nitrides, the results indicate that YFe10.5Mo1.5CxNy possess a higher Curie temperature and a larger saturation magnetization than YFe10.5Mo1.5Ny, which is of significance in the technical applications.
