Neutron powder diffraction studies indicate that PrFe10.5Mo1.5Nx retains the ThMn12-type structure, and nitrogen atoms occupy the interstitial 2b sites. According to the structure parameters, the crystal-field coefficients of Pr3+ in the PrFe10.5Mo1.5 compounds and their nitrides were calculated using the single-ion model. The results show that upon nitrogenation the easy magnetization direction of PrFe10.5Mo1.5 changes from easy plane to easy axis. As a preliminary attempt, magnetic powders based on PrFe10.5Mo1.5Nx were obtained with a maximum energy product of 16.6 MGOe at room temperature.
