Full-potential linearized augmented plane wave method has been employed to investigate the electronic and magnetic properties of Ru{sub 2}VSi Heusler alloy at optimized lattice parameter and in expanded lattice. Present computations predict that Ru{sub 2}VSi has a ferromagnetic ground state with an optimized lattice constant 5.952 Å. The compound in ambient conditions was found to have metallic character. However, increased value of lattice parameter induces 100% spin-polarization in the material at Fermi energy. Further, the band gap tends to increase and the material behaves as pure half-metallic at an increased value of lattice constant.
