Аннотация

Oxides with perovskite structure SrFeO₃ and SrCoO₃ are ancestors of wide range of technologically important substances, used as oxide ionic conductors. Previously we use the substitution of the cations in the B positions by high-charge ions Mo6+ W6+ Ta5+ Nb5+ to modify the properties of this class of oxygen-deficient oxides. Doping with these elements suppressed phase transitions in oxides based on cobalt-ferrite strontium-barium, reduced the size of nanodomains and rise chemical and structure stability of these oxides. Now we performed the theoretical study of the influence of A- and B-substitution on electronic structure of SrFeO₃ and SrCoO₃ in the order to clarify how the doping by high-charge cations affects the properties and electronic structure of oxides.
