The enhancement of magnetic properties of RE-TM hard magnet materials, such as RE2Fe17, upon nitriding is studied using the Wigner–Seitz (Voronoi) construct. In analogy with other RE-TM nitrides, it is concluded that nitrogen has a strong preference to occupy the octahedral 9e site in the 2:17 compounds, to the exclusion of the other proposed sites. Additional materials are suggested as candidates for nitriding on the basis of the availability of such an octahedral site. The site preference and its effect on the magnetism in RE2Fe17 is discussed in relation to the Wigner–Seitz cell of the atoms. The magnetic moments on the iron are shown to be correlated with the WS cell volumes, and this dependence differs from that associated with αFe.
