The calculations were performed by using the first-principle calculations of density functional theory. The lattice constant of Ba1−x V x S decreases with increasing concentration (x) of the V atom. We have found that the Ba0.75 V 0.25S and Ba0.5 V 0.5S compounds are half-metallic ferromagnets with total magnetic moments of 3 μ B per V atom, while for high concentration x = 0.75, the Ba0.25 V 0.75S becomes nearly half metallic due to broadening of 3d (V) states in the gap. The exchange coupling between the 3d (V) levels and conduction bands is ferromagnetic, confirming the magnetic nature of Ba1−x V x S compounds.Show less >
