39K and 87Rb Nuclear Magnetic Resonance in the Pyrochlore Superconductors AOs2O6 (A=K, Rb)
K. Arai, J. Kikuchi, K. Kodama +4
This paper has been withdrawn by the authors, since a crucial assumption in the analysis of the data was found to be incorrect from the later experiments.
High Pressure Effects on Superconductivity in the beta-pyrochlore Oxides AOs2O6 (A=K, Rb, Cs)
Takaki Muramatsu, Shigeki Yonezawa, Yuji Muraoka +1
Recently new pyrochlore oxides superconductors AOs2O6 (A=K,Rb,Cs) were found and we measured the pressure dependence of magnetization up to 1.2 GPa in order to deduce the pressure…
Heat-capacity anomalies in the presence of high magnetic fields in the spin-chain compound, Ca3Co2O6
E. V. Sampathkumaran, Z. Hiroi, S. Rayaprol +1
Heat-capacity behavior in the presence of externally applied magnetic field (H) up to 140 kOe is investigated (2-35 K) for the quasi-1-dimensional compound, Ca3Co2O6, believed to o…
Photocarrier injection and the I-V characteristics of La0.8Sr0.2MnO3/SrTiO3:Nb heterojunctions
Takaki Muramatsu, Yuji Muraoka, Zenji Hiroi
Oxide heterojunctions made of p-type L0.8Sr0.2MnO3 (LSMO) and niobium-doped n-type SrTiO3 (STO:Nb) have been fabricated by the pulsed laser deposition (PLD) technique and are chara…
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…
Possible Anisotropic Order Parameter in Pyrochlore Superconductor KOsO Probed by Muon Spin Rotation
A. Koda, W. Higemoto, K. Ohishi +5
Magnetic penetration depth () in a pyrochlore superconductor KOsO was studied by means of muon spin rotation (\msr). The temperature dependence of transverse spin relaxa…
