Nd(Fe,Mo)/sub 12/N/sub x/ compounds and magnets

The Mo-substituted Nd(Fe,Mo)/sub 12/N/sub x/ compounds are investigated. The ThMn/sub 12/ crystal structure has been obtained for the RFe/sub 11/Mo composition by optimizing the solution treatment temperature, and the magnetic properties of RFe/sub 11/MoN/sub x/ have been measured. The NdFe/sub 11/MoN/sub x/ shows large saturation magnetization and Curie temperature, and has a higher anisotropy field than the NdFe/sub 11/TiN/sub x/. The magnet fabrication has been carried out by mechanical alloying and rapid quenching process.<
