Study of Ru2VGe and Ru2VSb: High-spin polarized and half-metallic Heusler alloys
Electronic and magnetic properties of Ru2VGe and Ru2VSb have been investigated by ab-initio. The optimized equilibrium lattice parameters were found to be 6.032 A for Ru2VGe and 6.272 A for Ru2VSb. Both the materials have ferromagnetic ground states and V mainly contributes to the magnetic properties in these materials. The highly spin-polarized half-metallic materials have integral magnetic moments of 1.0 µ B for Ru2VGe and 2.0 µ B for Ru2VSb with an energy gap of 0.095 eV for Ru2VGe and 0.186 eV for Ru2VSb in the spin-down channel.
