High-pressure synthesis of BaVO3: A new cubic perovskite Original Research Article

A new cubic perovskite BaVO3 was synthesized by high-pressure synthesis at 15 GPa, and 1350 °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 a=3.94288(3) Å at room temperature and had Fermi-liquid characteristics as SrVO3 down to the lowest temperature.
