Pressure effects in the triangular layered cobaltites NaxCoO2
G. Garbarino, M. Monteverde, M. Nunez Regueiro +3
We have measured transport properties as a function of temperature and pressure up to 30GPa in the NaxCoO2 system. For the x=0.5 sample the transition temperature at 53K increases…
Large enhancement of the thermopower in NaCoO at high Na doping
Minhyea Lee, Liliana Viciu, Lu Li +6
Research on the oxide perovskites has uncovered electronic properties that are strikingly enhanced compared with those in conventional metals. Examples are the high critical temper…
Low-lying electronic structure of doped triangular cobaltates
A. P. Kuprin, D. Qian, Y. -D. Chuang +3
We report detailed Fermi surface topology and quasiparticle dynamics of the host cobaltate Na0.7CoO2. A direct mapping of the Fermi surface is carried out by angle-resolved photoem…
Crystal Structure and Elementary Properties of NaxCoO2 (x = 0.32, 0.5, 0.6, 0.75, and 0.92) in the Three-Layer NaCoO2 Family
L. Viciu, J. W. G. Bos, H. W. Zandbergen +7
The crystal structures of the NaxCoO2 phases based on three-layer NaCoO2, with x=0.32, x=0.51, x=0.60, x=0.75 and x=0.92, determined by powder neutron diffraction, are reported. Th…
Absence of conventional charge ordering in Na0.5CoO2 from a high resolution neutron diffraction study
A. J. Williams, J. P. Attfield, M. L. Foo +1
The structure of Na0.5CoO2, the low temperature insulator that separates the magnetic and superconducting regions in the NaxCoO2.yH2O phase diagram, is studied by high resolution p…
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…
