Beschreibung
Zusammenfassung:The mechanism of d-pairing with account of antiferromagnetic spin fluctuations was considered. The thermodynamics of d-wave pairing in cuprate superconductors was calculated. For the calculation the method of functional integrals was used. It has been shown that the temperature dependence of specific heat corresponds to d-pairing. The value of the jump of specific heat Delta / gamma T sub(c) for the compounds YBa sub(2)Cu sub(3)O sub(6.63) was given.
