LaBaNiO4: A Fermi glass
A. Schilling, R. DellAmore, J. Karpinski +4
Polycrystalline samples of LaSr1-xBaxNiO4 show a crossover from a state with metallic transport properties for x = 0 to an insulating state as x -> 1. The end member LaBaNiO4 with…
Spin fluctuations, magnetic long-range order and Fermi surface gapping in NaxCoO2
T. F. Schulze, M. Bruehwiler, P. S. Haefliger +5
In this study an extended low energy phase diagram for NaxCoO2 is experimentally established with emphasis on the high x range. It is based on systematic heat capacity studies on b…
NaxCoO2: Enhanced low-energy excitations of electrons on a 2D triangular lattice
M. Brühwiler, B. Batlogg, S. M. Kazakov +2
To elucidate the low-energy excitation spectrum of correlated electrons on a 2D triangular lattice, we have studied the electrical resistance and specific heat down to 0.5 K and in…
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…
Anomaly in YBa2Cu4O8 charge distribution below Tc: a zero-field muSR study
P. Carretta, A. Keren, J. S. Lord +3
Zero-field SR measurements in Cu isotope enriched and natural YBaCuO powders are presented. The temperature dependence of the relaxation rate is charact…
Evidence for two electronic components in NaxCoO2 (x = 0.7-0.75)
M. Brühwiler, B. Batlogg, S. M. Kazakov +1
Thermodynamic and transport measurements on NaxCoO2 (x ~ 0.7-0.75) over a wide temperature range reveal a strongly enhanced low energy excitation spectrum. The zero-field specific…
