Structural phase transition in the superconducting pyrochlore oxide Cd2Re2O7

Authors report a structural phase transition found at Ts=200 K in a pyrochlore oxide Cd2Re2O7 which shows superconductivity at Tc=1.0 K. powder XRD experiments indicate that the phase transition is of the second-order, from a high-temperature phase with the ideal cubic pyrochlore structure (space gr...
