Magnetic Phase Transition at 88 K in Na0.5CoO2 revealed by 23Na-NMR investigations
B. Pedrini, J. L. Gavilano, S. Weyeneth +6
Na0.5CoO2 exhibits a metal-insulator transition at 53 K upon cooling. The nature of another transition at 88 K has not been fully clarified yet. We report the results of measuremen…
Evidence for a smooth superconductor to normal state transition for nonzero applied magnetic field in RbOs2O6
T. Schneider, R. Khasanov, J. Karpinski +2
The effect of the magnetic field on the critical behavior of RbOs2O6 is investigated. We present and analyze magnetization data, revealing remarkable consistency with a magnetic fi…
Al substitution in MgB2 crystals: influence on superconducting and structural properties
J. Karpinski, N. D. Zhigadlo, G. Schuck +11
Single crystals of Mg1-xAlxB2 have been grown at a pressure of 30 kbar using the cubic anvil technique. Precipitation free crystals with x < 0.1 were obtained as a result of optimi…
Influence of carbon substitution on the heat transport in single crystalline MgB2
A. V. Sologubenko, N. D. Zhigadlo, S. M. Kazakov +2
We report data on the thermal conductivity κ(T,H) in the basal plane of hexagonal single-crystalline and superconducting Mg(B_{1-x}C_x)_2 (x= 0.03, 0.06) at temperatures between 0.…
A Point-Contact Study of the Superconducting Gaps in Al-Substituted and C-Substituted MgB_2 Single Crystals
R. S. Gonnelli, D. Daghero, G. A. Ummarino +6
We present the results of directional point-contact spectroscopy in state-of-the-art Mg_{1-x}Al_xB_2 and Mg(B_{1-y}C_{y})_2 single crystals produced at ETH, Zurich. Fitting the con…
