WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. We make the first report that a metallic pyrochlore oxide Cd2Re2O7, exhibits type II superconductivity at 1.1 K. The pyrochlore oxide is known to be a geometrical frustrated system, which includes the tetrahedral network of magnetic ions. A large number of … WebMay 23, 2002 · Electronic properties of the metallic pyrochlore oxide Cd 2 Re 2 O 7 are studied by means of electrical resistivity and Hall measurements.
