Iron-rich ternary intermetallic compound Nd-3(Fe, Mo)(29) with the Nd-3(Fe, Ti)(29)-type monoclinic structure and its nitride were prepared. The intrinsic magnetic properties, magnetic phase transitions, and the magnetocrystalline anisotropy, have been investigated. The results show that the Curie temperature of Nd-3(Fe, Mo)(29) nitride is 675 K, which is 70.9 % higher than that of parent compound (395 K), the saturation magnetization as and anisotropy fields H-A are 151.0 Am-2/kg and 14.0 T at 4.2 K, 116.0 Am-2/kg and 1.6 T at 300 K for Nd-3(Fe, Mo)(29) compound, 161.0 Am-2/kg and 18.0 T at 4.2 K, 143.5 Am-2/kg and 4.2 T at 300 K for Nd-3(Fe, Mo)(29 )N-x nitride, respectively; the magnetocrystalline anisotropy of the Nd-3(Fe, Mo)(29) compound is planar above about 230 K and easy cone from 4.2 to 230 K, after nitrogenation, the spin reorientation phenomenon was no longer observed.
