EN

We present the ab initio investigations of the electronic and magnetic properties of magnetocaloric Gd(Ni_{1-x}Fe_x)_3 alloys. To simulate fractional concentrations the supercell approach was implemented and different configurations of iron atoms were considered. Energetical analysis of site preference and magnetic order was performed. The concentration dependence of the averaged total and local magnetic moments and of the valence band photoemission spectra are presented and discussed in reference to experimental data.
