Abstract

The structure and magnetic properties of RFe12-xMox series and their nitrides with R=Y,Gd,Nd and x=0.8,1.0,1.5,2.0,2.5 have been studied by x-ray-diffraction and magnetic measurements. It is found that with the increment of Mo content x, the lattice parameters increase, whereas the saturation magnetization, Curie temperature, and anisotropy field decreases in the RFe12-xMox series. Upon nitrogenation lattice parameters, saturation magnetization, and Curie temperature increase. Correspondingly, the easy c-axis magnetocrystalline anisotropy of the Fe sublattice decreases in YFe12-xMoxNy and GdFe12-xMoxNy but increases in NdFe 12-xMoxNy although its variation with the Mo content is the same as in their original counterparts. NdFe 12-xMoxNy compound in the low Mo content shows great potential for permanent magnet applications.
