Abstract

Superconducting transition temperature is calculated for differently doped bilayer cuprates. Superexchange is assumed to be the dominating mechanism of high-temperature superconductivity, but the contribution from the phonon potential is not negligible, which qualitatively explains the observed weak isotopic effect. The calculated value 2 $\Delta_{max}/k_B T_C \simeq 4.5$ is close to the experiment in the case of optimum doping.
