Zusammenfassung
On the basis of first principles density functional calculations, we investigated the effect of spin flip and hole doping on the spin, charge and lattice degrees of freedom in the square planar CuO(2) layers of the high-T (c) cuprate superconductors. The local responses of the CuO(2) layers to these point defects appear as spatially extended spin-charge-lattice coupled polarons in ferromagnetic clusters and hence introduce heterogeneity. The results demonstrate the need to treat the spin, charge and lattice degrees of freedom on an equal footing in describing the high-T (c) superconductivity.
