Abstract
A precisive calculation of specific heat contributions of vortex liquids and solids in type-II superconductor is presented. We use the self-consistent method in the presence of magnetic field for the Ginzburg-Landau description of thermal fluctuations effects in the vortex liquids. Self-consistent calculation of the specific heat summing over all Landau levels is valid for arbitrary values of the magnetic field not too close to Hc1. Our results are in good agreement with the experimental data in a wide region around Tc, including both the vortex liquid below Tc and the normal state above Tc. Our calculation shows that the specific heat behaves as a long tail which persists far into the normal state, indicating the residual superconductivity above Tc.
