The magnetic and electronic properties of double perovskite Sr 2-xLaxVMoO6 (x = 0:9-1:2) polycrystalline bulk samples have been investigated. Magnetization and electrical resistivity measurements indicate that Sr2-xLaxVMoO6 is an antiferromagnetic metal with an antiferromagnetic transition temperature in the range 123-146 K. X-ray photoemission spectroscopy measurements reveal that Mo has a tetravalent state (Mo4+) and V has a trivalent state (V 3+) in SrLaVMoO6. These results indicate that V 3+ (3d2) ions are antiferromagnetically coupled with Mo4+ (4d2) ions. Electron-doping effects of Sr 2+xLaxVMoO6 by La substitution differed from those of half-metallic Sr2-xLaxFeMoO6. This can be qualitatively explained by considering the different electron-doped orbitals and ordering ratios of B-site ions between Sr2-xLa xVMoO6 and Sr2-xLaxFeMoO6 (Mo/V or Mo/Fe).
