Abstract
We report the first pyrochlore oxide superconductor Cd2Re2O7. Resistivity, magnetic susceptibility, and specific heat measurements on single crystals evidence a bulk superconductivity at 1 K. Another phase transition found at 200 K suggests, that a peculiar electronic structure lies behind the super conductivity.
