摘要：

We report the superconducting properties of the pyrochlore oxide Cd2Re2O7. The bulk superconducting transition temperature T-c is about 1.0 K, and the upper critical field H-c2 determined by the measurement of specific heat under magnetic fields is 0.29 T. The superconducting coherence length is estimated to be 34 nm. Specific heat data measured on single crystals suggest that the superconducting gap of Cd2Re2O7 is nodeless.
