Abstract

Evidence of another phase transition at 120 K in the metallic pyrochlore oxide Cd2Re2O7, following a structural transition at 200 K and followed by a superconducting transition at 1.0 K, is obtained by resistivity, magnetoresistance, specific heat, and X-ray diffraction measurements. The results indicate unique successive structural and electronic transitions in the pyrochlore compound, revealing an interesting interplay between the crystal and electronic structures on the itinerant electron system in the pyrochlore lattice.
