Abstract
The exchange enhancement of electron-phonon coupling has been calculated for a three- and two-dimensional superconductor. The critical temperature has been determined taking into consideration the electron-phonon attraction, the spin fluctuations effect, and Coulomb repulsion. The two-dimensional spin fluctuations and Coulomb contributions were calculated. TheT c dependence on the productUN(0) has been analyzed in both the three- and two-dimensional cases.
