摘要

Iron-rich ternary intermetallic compound Nd_3 (Fe, Mo)_29 with the Nd_3 (Fe, Ti)_29-type mono- clinic 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 70.9/100 higher than that of parent compound (395 K), the satura- Tion magnetization σs 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 300K for Nd_3 (Fe, Mo)_29N_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 K to 230 K, after nitrogenation, the spin reori- entation phenomenon was no longer observed.
