Abstract

A high-resolution ac quasiadiabatic calorimeter has been employed to measure the heat-capacity anomaly associated with the normal-superconducting transition of several slightly twinned YBa2Cu3O7 single-crystal samples. The heat-capacity anomaly from one of the samples displays a very sharp 1090% jump on the high-temperature side of anomaly and can be described by a mean-field model based on the BCS theory.
