Abstract
An expression for the difference in thermodynamic potentials Ωs-Ωn of the superconducting and normal states is derived by use of thermodynamic Green’s functions. The change in the heat capacity Cs-Cn in the normal-to-superconducting phase transition in the presence of a periodic magnetic order and spin fluctuations is obtained. The jump δC in the specific heat at superconducting transition temperature is calculated. The variation of electronic heat capacity C with temperature for T≶Tc is studied. It is noted that the presence of magnetic order reduces the jump in specific heat at Tc.
