A new cubic perovskite BaVO3 was synthesized by high-pressure synthesis at 15 GPa, and 1350 degrees C. Contrary to our expectations that lattice expansion by Ba substitution for Sr would lead to non-centrosymmetric tetragonal distortion, BaVO3 preserved its cubic crystal structure with alpha=3.94288(3) A at room temperature and had Fermi-liquid characteristics as SrVO3 down to the lowest temperature.
