Abstract :
Results of X-ray diffraction studies and magnetic measurements performed on Y2Fe17-xMx compounds (M=Mo,V or Ti) and their nitrides are reported. By nitrogenation of the parent alloys, the lattice parameters increase significantly, this fact determining a substantial increase of the Curie temperature. The volume effects on the variation of Curie temperatures in Y2Fe17-xMxNy decrease when increasing M content. The dlnTc/dlnV values show a linear dependence on the Curie temperatures. The experimental data are analysed in a model which supposes that the greatest fraction of iron 3d electrons are localized
