The NdFe10.5V1.5Nx compounds with different nitrogen content have been synthesized. The dependence of magnetic properties at room temperature on the nitrogen content was investigated in order to give evidence of the importance of the nitrogen content on the magnetic anisotropy of the rare earth sublattice. In the meantime, the theoretical calculations were performed to analyze the nitrogen content dependence of the magnetocrystalline anisotropy constants K1,2, as well as the anisotropy field Ha in the NdFe10.5V1.5Nx. The results confirmed that the second-order crystal-field parameter A20 is dominant and, in the nitrides, the chief contribution to A20 comes from nitrogen located at 2b sites. Finally, the increase of nitrogen content will first turn the easy-plane magnetocrystalline anisotropy of the rare earth sublattice into easy-axis one and then enhance it linearly to a much larger value, which is in quite good agreement with experiment.
