Abstract:

We introduce briefly the principal ideas of a new model approach to the strongly correlated oxides like cuprates (YBa2Cu3O6+x, La2-xSrxCuO4, La2CuO4+delta,...), manganites (La1-x,SrxMnO3,...), nickellates (La2NiO4+delta), bis-muthates ((K, Ba)BiO3) as systems where the nonisovalent substitution promotes the local disproportionation reaction with the formation of the polar (electron and hole) pseudo-Jahn-Teller (PJT) centers phase being a system of the local singlet or triplet bosons moving in a lattice of the hole PJT centers. The unconventional properties of the substituted strongly correlated oxides are connected with an active interplay of the charge, spin, orbital and local structural (or PJT) modes taking account of the strong charge inhomogeneity, multi-granularity, static and dynamic phase separation and percolation phenomena.
