- Université Djillali Liabès de Sidi Bel-Abbés, Laboratoire de Modélisation et Simulation en Sciences des Matériaux (Algeria)
In this letter, structural, electronic structure, and magnetic properties of Ru{sub 2}FeSi{sub 1−x}Ge{sub x} were analyzed for the first time in the stable B2 phase by using the first-principle calculation. The exchange and correlation potentials are described by using generalized gradient approximations (GGA) The B{sub 2} structure is found to be energetically more favorable than the L2{sub 1} structure. It was found that the lattice parameters increase linearly with increasing x. For all the range studied, the Ru{sub 2}FeSi{sub 1−x}Ge{sub x} alloys exhibit a metallic character. The origin of magnetic moment is due to the exchange splitting of Fe-d states, and the atomic magnetic moment of the present material originates mainly from Fe atom.
