The structural, elastic, magnetic properties, as well as electronic structure and chemical bonding picture of new oxide 3d(1)-perovskite BaVO3, recently synthesized, were systematically investigated involving the first-principles FLAPW-GGA calculations. The obtained results are discussed in comparison with available experimental data, as well as with those obtained before for isostructural and isoelectronic SrVO3 perovskite. (C) 2015 Elsevier B.V.
