We studied the physical properties of Sr2 VO4 with a K2 NiF4 structure in polycrystalline forms synthesized under various different conditions. We found that stoichiometric samples or those with nominal hole doping into the d1 state of the V ion exhibit insulating behavior with an antiferromagnetic interaction between V moments, whereas those with nominal electron doping exhibit metallic conduction and ferromagnetic interaction. A structural phase transition at Tc ∼ 100 K, which is likely to be associated with the orbital ordering of the V4+ ion, is observed only in the former sample exhibiting a sharp drop in the magnetic susceptibility at the same temperature, whereas no structural anomaly was observed for the sample exhibiting a cusp in the magnetic susceptibility at ∼50 K.
