Description
It has been shown that in a strongly correlated system there is multiple exchange interaction, the detailed derivation of which will be given here. From the numerical calculations of Tc,Tc vs. x and y for La2-xSrxCuO4 and Y1Ba2Cu3O7-y, the small isotope effect, and some explanations for the observed phenomena, this paper once again affirms that high-Tc SC (superconductivity) is almost completely caused by the multiple exchange interaction and layer tunnelling coupling. This paper also concludes that the Cooper pair consists of Opσ holes in CuO2. (author). 20 refs, 4 figs
