Rattling-Induced Superconductiviy in the Beta-Pyrochlore Oxides AOs2O6
Yohei Nagao, Jun-ichi Yamaura, Hiroki Ogusu +2
The superconducting properties of two beta-pyrochlore oxides, CsOs2O6 and RbOs2O6, are studied by thermodynamic and transport measurements using high-quality single crystals. It is…
Unique Phase Transition on Spin-2 Triangular Lattice of Ag2MnO2
Hiroyuki Yoshida, Sascha Ahlert, Martin Jansen +3
Ag2MnO2 is studied as a possible candidate compound for an antiferromagnetic XY spin model on a triangular lattice. In spite of the large Curie-Weiss temperature of -430 K found in…
Vortex Redistribution below the First-Order Transition Temperature in the β-Pyrochlore Superconductor KOs_2O_6
T. Shibauchi, M. Konczykowski, C. J. van der Beek +5
A miniature Hall sensor array was used to detect magnetic induction locally in the vortex states of the -pyrochlore superconductor KOsO. Below the first-order transition…
Extremely strong-coupling superconductivity and anomalous lattice properties in the beta-pyrochlore oxide KOs2O6
Z. Hiroi, S. Yonezawa, Y. Nagao +1
Superconducting and normal-state properties of the beta-pyrochlore oxide KOs2O6 are studied by means of thermodynamic and transport measurements. It is shown that the superconducti…
Precise Control of Band Filling in NaxCoO2
Daisuke Yoshizumi, Yuji Muraoka, Yoshihiko Okamoto +5
Electronic properties of the sodium cobaltate NaxCoO2 are systematically studied through a precise control of band filling. Resistivity, magnetic susceptibility and specific heat m…
Chemical trends of superconducting properties in pyrochlore oxides
Zenji Hiroi, Jun-Ichi Yamaura, Shigeki Yonezawa +1
Chemical trends of fundamental superconducting parameters and normal-state properties are described for a family of pyrochlore oxide superconductors. Particularly, the change of Tc…
