Specific Heat of Na0.35CoO2,1.3H2O: Effects of Sample Age; Non-Magnetic Pair Breaking, Two Energy Gaps, and Strong Fluctuations in the Superconducting State
N. Oechsler, R. A. Fisher, N. E. Phillips +3
The specific heats of three samples of Na0.35CoO2,1.3H2O show an evolution of the superconductivity, and its ultimate disappearance, with increasing sample age. An overall increase…
Hydration phase diagram for sodium cobalt oxide Na0.3CoO2*yH2O
M. L. Foo, T. Klimczuk, R. J. Cava
The hydration phase diagram for sodium cobalt oxyhydrate, Na0.3CoO2*yH2O (y=0, 0.6, 1.3), was determined as a function of relative humidity at 298K. It is found that greater than 7…
Heat Capacity of NaCoO1.3HO, a New Two-Gap Superconductor: Comparison with the Heat Capacity of MgB
N. Oeschler, R. A. Fisher, N. E. Phillips +3
The superconducting-state heat capacity of NaCoO1.3HO shows unusual, marked deviations from BCS theory, at all temperatures. At low temperatures the heat…
Sodium Ion Ordering in NaxCoO2
H. W. Zandbergen, M. L. Foo, Q. Xu +2
The layered sodium cobalt oxide NaxCoO2 is studied by electron diffraction for a wide range of sodium contents, 0.15<x<0.75. An extensive series of ordered Na ion-Na vacancy superl…
Unconventional superconductivity in NaCoO1.3DO and proximity to a magnetically ordered phase
Y. J. Uemura, P. L. Russo, A. T. Savici +8
Muon spin relaxation (SR) measurements on the new layered cobalt oxide superconductor NaCoO1.3HO and its parent, non-superconducting compounds, have re…
Low Temperature Spin Freezing in Dy2Ti2O7 Spin Ice
J. Snyder, B. G. Ueland, J. S. Slusky +3
We report a study of the low temperature bulk magnetic properties of the spin ice compound Dy2Ti2O7 with particular attention to the (T < 4 K) spin freezing transition. While this…
