Аннотация: The effect of the magnetic correlators on the spin polaron superconducting phase is studied in terms of 2D Kondo lattice model. It is shown that hopping integrals are renormalized by the magnetic correlators and as a result the Tc phase diagram is changing significantly. By computation the effect of magnetic correlation functions oПоказать полностьюn the concentration dependence of T c was analysed and their substantial role in description of doped antiferromagnets is demonstrated. The obtained phase diagram is in qualitative agreement with experimental data for temperature dependence of the superconducting phase transition with d-type symmetry in cuprates. © 2010 IOP Publishing Ltd.
