摘要: We report the influence of V deficiency on structure, transport, and magnetic properties polycrystalline LaVO3. Up to 10% V-deficient samples were synthesized using standard solid state chemistry route. Structural spectroscopic studies show that it intricately modifies lattice parameters oxidation states V. Further temperature dependent resistivity data reveal induces an enhancement in activation energy. The paramagnetic moment these depends net composition while all exhibit a paramagnetic-to-antiferromagnetic transition at about 140 K. These distinct are understood owing presence multiple oxidations V, predominantly V3+ V4+, nonstoichiometric
