Effect of interlayer interaction on the specific heat of high-Tc superconductors

Abstract

The effect of interlayer interactions on the electronic specific heat of high-Tc layered superconductors has been studied within the framework of the Hirsch model. In the present paper we extend our previous work in order to evaluate the expression for specific heat. It is shown that the inclusion of interlayer interactions suppresses the height of the jump in the specific heat at Tc.
