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 Na $_{0.3}$ CoO $_{2}$ $\cdot$ 1.3H $_{2}$ O, a New Two-Gap Superconductor: Comparison with the Heat Capacity of MgB $_{2}$

N. Oeschler, R. A. Fisher, N. E. Phillips +3

The superconducting-state heat capacity of Na $_{0.3}$ CoO $_{2}$ $\cdot$ 1.3H $_{2}$ O shows unusual, marked deviations from BCS theory, at all temperatures. At low temperatures the heat…

Unconventional superconductivity in Na $_{0.35}$ CoO $_{2} \cdot$ 1.3D $_{2}$ O and proximity to a magnetically ordered phase

Y. J. Uemura, P. L. Russo, A. T. Savici +8

Muon spin relaxation ( $μ$ SR) measurements on the new layered cobalt oxide superconductor Na $_{0.35}$ CoO $_{2} \cdot$ 1.3H $_{2}$ O and its parent, non-superconducting compounds, have re…
