Fluctuation contributions to the heat capacity of superconducting thin films
… superconductors. The presence of thermodynamic fluctuations causes a breakdown of mean field theory if one gets close enough to the transition temperature, T. For a pure bulk superconductor, the temperature region over which thermodynamic fluctuations become important is inuneasurably small. For …

Heat capacity measurements of yttrium barium(2)copper(3)oxygen(7-delta) near T(c): Fluctuation effects in a bulk superconductor
… This divergence is indicative of the presence of fluctuation contributions and is due to the exceptionally short Ginzburg-Landau coherence length of this material. Because there is considerable uncertainty in the temperature of cross-over from mean-field to critical behavior, the zero-field heat …
