Magnetic Properties of NdTiFe₁₁N_0.5 and YTiF₁₁N_0.5

The structural and magnetic properties of NdTiFe₁₁N_0.5 and YTiFe₁₁N_0.5 have been studied. The nitrides retain the tetragonal ThMn₁₂ structure and their unit cell volumes slightly increase. The interstitial nitrogen atoms are found to increase the Curie temperature and saturation magnetization of the compounds, and especially have a strong effect on the magnetocrystalline anisotropy.
