Local moment, itinerancy and deviation from Fermi liquid behavior in NaCoO for
L. Balicas, Y. J. Jo, G. J. Shu +2
Here we report the observation of Fermi surface (FS) pockets via the Shubnikov de Haas effect in NaCoO for and 0.84, respectively. Our observations indicate that…
^{59}Co NMR evidence for charge ordering below T_{CO}\sim 51 K in Na_{0.5}CoO_2
F. L. Ning, S. M. Golin, K. Ahilan +3
The CoO layers in sodium-cobaltates NaCoO may be viewed as a spin triangular-lattice doped with charge carriers. The underlying physics of the cobaltates…
Sodium vacancy ordering and the co-existence of localized spins and itinerant charges in NaxCoO2
F. C. Chou, M. -W. Chu, G. J. Shu +6
The sodium cobaltate family (NaxCoO2) is unique among transition metal oxides because the Co sits on a triangular lattice and its valence can be tuned over a wide range by varying…
Searching for Stable Na-ordered Phases in Single Crystal Samples of gamma-NaxCoO2
G. J. Shu, Andrea Prodi, S. Y. Chu +3
We report on the preparation and characterization of single crystal gamma phase NaxCoO2 with 0.25 < x < 0.84 using a non-aqueous electrochemical chronoamperemetry technique. By car…
