Abstract

RFe_10.5Mo_1.5C_x (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 YFe_10.5Mo_1.5C_xN _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 RFe_10.5Mo_1.5C_x series, and the carbon atoms also affect the magnetocrystalline anisotropy. The easy axial anisotropy of NdFe_10.5Mo_1.5C_x and DyFe_10.5Mo _1.5C_x is enhanced. As to the nitrides, the results indicate that YFe_10.5Mo_1.5C_xN_y possess a higher Curie temperature and a larger saturation magnetization than YFe_10.5Mo_1.5N_y, which is of significance in the technical applications.
