Abstract

Experiments have revealed that some samples of high-T c ceramic superconductors possess a double peak structure in the specific heat. We shall show that within a BCS formalism it is possible to explain this double peak as a pure superconduction phenomenon. An important feature of the model is the onsite pairing interaction term which turns out to determine the difference between the two peaks.
