Influence of polaron effects on superexchange interaction. Isotopic shifts of TN, Tc and T* in laminated copper oxides

The compact formula for the parameter for the magnetic ions superexchange interaction through intermediate anions with an account of the polaron effects both on the magnetic ions and intermediate anions is obtained. It is applied for the analysis of the basic peculiarities of these types of temperature in the layered cuprates on the HTSC basis: the Neel temperature (TN), critical temperatures of the transition into the superconducting state (Tc) and characteristic temperatures of the normal phases pseudogap state (T*). The calculations are based on the scenario of competition of the superconducting phase with the charge-current waves phase. The agreement of the calculation with the experiment testifies to the benefit of the above scenario
