Physical properties of new superconductor Cd2Re2O7 with pyrochlore-type structure

111Cd NMR study has been performed in the normal state of superconducting pyrochlore oxide Cd2Re2O7. A large orbital susceptibility is identified from K-*y analysis. The sharp decreases of both K and T1-1 below T* suggests a decrease in density of states which is apparently caused by a developing pa...

Zusammenfassung:111Cd NMR study has been performed in the normal state of superconducting pyrochlore oxide Cd2Re2O7. A large orbital susceptibility is identified from K-*y analysis. The sharp decreases of both K and T1-1 below T* suggests a decrease in density of states which is apparently caused by a developing partial energy gap at the Fermi surface.
