Thermodynamics of high-T_C materials in the rotating antiferromagnetism theory

In high-temperature superconductors the pseudogap energy affects the electronic specific-heat data for doping densities smaller than the optimal point. Within the rotating antiferromagnetism theory I calculated the superconducting and rotating antiferromagnetic parameters, then got the phase diagram. Also, the specific-heat coefficient and entropy are evaluated as a function of temperature. In addition, the doping dependence of the condensation energy, specific-heat anomaly, and entropy at T_C are calculated. Experimental data are analyzed by focusing on the trends in the doping and temperature dependence. As far as the above quantities are concerned this theory yields very good agreement with experiment, and can therefore be said to be applicable to high-temperature superconductors.
