摘要: We have studied the interplay between orbital ordering, Jahn-Teller and ${\mathrm{GdFeO}}_{3}$-type lattice distortions in perovskite-type transition-metal oxides using model Hartree-Fock calculations. It has been found that covalency A-site cations oxygens causes interaction distortions. The present calculations explain why d-type distortion ordering compatible with it are realized ${\mathrm{LaMnO}}_{3},$ ${\mathrm{YVO}}_{3},$ ${\mathrm{YTiO}}_{3}.$
