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…
Unusual magnetic properties of the low-dimensional quantum magnet Na2V3O7
J. L. Gavilano, E. Felder, D. Rau +5
We report the results of low-temperature measurements of the specific heat Cp(T), ac susceptibility chi(T) and 23Na nuclear magnetic resonance NMR of Na2V3O7. At liquid He temperat…
Kondo Behavior of U in CaB
G. A. Wigger, E. Felder, S. Weyeneth +2
Replacing U for Ca in semiconducting CaB at the few at.% level induces metallic behaviour and Kondo-type phenomena at low temperatures, a rather unusual feature for U impuritie…
Percolation and Colossal Magnetoresistance in Eu-based Hexaborides
G. A. Wigger, C. Beeli, E. Felder +3
Upon substituting Ca for Eu in the local-moment ferromagnet EuB, the Curie temperature decreases substantially with increasing dilution of the magnetic sublattice and is…
Strong Electron-Phonon Coupling in Superconducting MgB: A Specific Heat Study
Ch. Wälti, E. Felder, C. Degen +4
We report on measurements of the specific heat of the recently discovered superconductor MgB in the temperature range between 3 and 220 K. Based on a modified Debye-Einstein mo…
Thermal conductivity and specific heat of the linear chain cuprate SrCuO: Evidence for thermal transport via spinons
A. V. Sologubenko, E. Felder, K. Gianno +3
We report measurements of the specific heat and the thermal conductivity of the model Heisenberg spin-1/2 chain cuprate SrCuO at low temperatures. In addition to a near…
