Abstract

NdFe10Mo2N0.5 samples were prepared by heating fine NdFe10Mo2 powders in N2 gas. The nitrided material maintains the ThMn12-type structure but with a unit cell volume about 3% larger than in the original compound. Neutron diffraction experiments showed that the nitrogen atoms occupy the interstitial 2b sites and the Mo atoms the 8i sites consistent with the Mössbauer data. The Curie temperature is greatly enhanced by about 150 K. The magnetocrystalline anisotropy changed strongly from plane anisotropy in NdFe10Mo2 to uniaxial anisotropy in NdFe10Mo2N0.5 at room temperatures. The changes in the local crystallographic and electronic structure can explain the strong uniaxial anisotropy of the nitrided material.
