Abstract

We calculate, via Monte Carlo simulations, the fluctuation contribution to the specific heat of a Ginzburg-Landau-Wilson model for a single-crystal high-temperature superconductor. The result resembles that measured by Salamon et al., both in the sharply peaked structure that replaces the usual Bardeen-Cooper-Schrieffer step, and especially in the reduction of this peak by magneticfield-induced frustration. The critical region of the model is probably broader than that measured.
