We investigated the structural and physical properties of Sr x (Nb 1-y V y ) O3 compounds. Powder x-ray diffraction analysis indicated that the samples with x=0.9 and 0 ≤ y ≤ 0.4 were nearly single phase of the cubic perovskite structure. For the samples with y ≤ 0.1, electrical resistivity (ρ) exhibited metallic behavior at temperatures below 300K, while for the samples with 0.2 ≤ y ≤ 0.4, ρ showed semiconducting behavior. Since the ln ρ -vs- T-1/4 curves were found to be pseudo-linear, the electrical conduction of the samples with 0.2 ≤ y ≤ 0.4 were likely due to variable-range hopping of carriers. For the sample with y=0, the magnetic susceptibility (χ) exhibited Curie-Weiss behavior below 300K. On the other hand, χ-vs- T curve of the samples with 0.1 ≤ y ≤ 0.4 had an anomalous broad peak at ~20K.
