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…
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.…
Anisotropic field dependence of the magnetic transition in Cu2Te2O5Br2
A. V. Sologubenko, R. Dell'Amore, H. R. Ott +1
We present the results of measurements of the thermal conductivity of Cu2Te2O5Br2, a compound where tetrahedra of Cu^{2+} ions carrying S=1/2 spins form chains along the c-axis of…
NMR and dc-susceptibility studies of NaVGe2O6
B. Pedrini, J. L. Gavilano, D. Rau +4
We report the results of measurements of the dc magnetic susceptibility chi(T) and of the 23Na nuclear magnetic resonance (NMR) response of NaVGe2O6, a material in which the V ions…
Temperature dependence of the upper critical field of high-Tc superconductors from isothermal magnetization data. Influence of a temperature dependent Ginzburg-Landau parameter
I. l. Landau, H. R. Ott
We show that the scaling procedure, recently proposed for the evaluation of the temperature variation of the normalized upper critical field of type-II superconductors, may easily…
Reinterpretation of the equilibrium magnetization of a Tl-based single crystal. Another phase transition in the mixed state of high-Tc superconductors?
I. L. Landau, H. R. Ott
We apply a recently developed scaling procedure for the analysis of the equilibrium magnetization M that was measured on a Tl-based single crystal and was recently reported in the…
