Abstract
We report the first observation of a specific-heat anomaly at the supe rconducting transition temperature of high-quality Nd1.85Ce0.15CuO4-de lta ceramics with T(c) = 24 K. The amplitude of the jump is DELTAC/T(c ) congruent-to 6 +/- 0.5 mJ/mole K. Application of a magnetic field H results in a broadening of the C(p) anomaly while the onset temperatur e remains field independent. We discuss the consistency of these resul ts with previous magnetic and transport measurements.
