A series of Y(Fe, M)12 compounds and their hydrides and nitrides, where M Ti, V, Mo, Cr, W, were prepared single phase. The effects of interstitial H and N atoms on the structural and magnetic properties have been studied by using the X-ray diffraction and magnetic measurements. The hydrides and nitrides still retain the tetragonal structure, but the unit cell volumes are expanded compared to their original counterparts. The saturation magnetization and Curie temperature are increased by both hydrogenation and nitrogenation, whereas the easy c-axis anisotropy related to the Fe-sublattice is enhanced in the hydrides but decreased in the nitrides.
