Abstract

The Schwinger–Dyson equations and equation for free energy are derived in the approximation of weak coupling interaction for antiferromagnetic spin fluctuations in high temperature superconductors. For the calculations the method of functional integrals was used. The thermodynamic of the system is calculated near T c and the evaluations of the parameter ∆C/γT c are given.
