Role of electron-electron and electron-phonon interaction effect in the optical conductivity of VO2
K. Okazaki, S. Sugai, Y. Muraoka +1
We have investigated the charge dynamics of VO2 by optical reflectivity measurements. Optical conductivity clearly shows a metal-insulator transition. In the metallic phase, a broa…
Thermal Conductivity of the Pyrochlore Superconductor KOs2O6: Strong Electron Correlations and Fully Gapped Superconductivity
Y. Kasahara, Y. Shimono, T. Shibauchi +4
To elucidate the nature of the superconducting ground state of the geometrically frustrated pyrochlore KOs2O6 (Tc=9.6K), the thermal conductivity was measured down to low temperatu…
New beta-Pyrochlore Oxide Superconductor CsOs2O6
Shigeki Yonezawa, Yuji Muraoka, Zenji Hiroi
The discovery of a new beta-pyrochlore oxide superconductor CsOs2O6 with Tc = 3.3 K is reported. It is the third superconductor in the family of beta-pyrochlore oxides, following K…
Correlations and Semimetallic Behaviors in Pyrochlore Oxide Cd2Re2O7
Z. Hiroi, M. Hanawa, Y. Muraoka +1
Electronic properties of the metallic pyrochlore oxide Cd2Re2O7 are studied by means of electrical resistivity and Hall measurements. Semimetallic band structures are revealed as e…
