Infrared Hall conductivity of NaCoO
E. J. Choi, S. H. Jung, J. H. Noh +5
We report infrared Hall conductivity of NaCoO thin films determined from Faraday rotation angle measurements. exhibits two types of hole…
Magnetic susceptibility study of hydrated and non-hydrated NaxCoO2-yH2O single crystals
F. C. Chou, J. H. Cho, Y. S. Lee
We have measured the magnetic susceptibility of single crystal samples of non-hydrated NaxCoO2 (x ~ 0.75, 0.67, 0.5, and 0.3) and hydrated Na0.3CoO2-yH2O (y ~ 0, 0.6, 1.3). Our mea…
Structural transition in NaxCoO2 with x near 0.75 due to Na rearrangement
Q. Huang, B. Khaykovich, F. C. Chou +3
We report neutron powder diffraction measurements on a series of NaxCoO2 samples with x near 0.75 which were prepared under different synthesis conditions. Two different crystal st…
Electrochemical De-intercalation, Oxygen Non-stoichiometry, and Crystal Growth of NaxCoO2-d
F. C. Chou, E. T. Abel, J. H. Cho +1
We report a detailed study of de-intercalation of Na from the compound NaxCoO2-d using an electrochemical technique. We find evidence for stable phases with Na contents near the fr…
Thermodynamic and Transport Measurements on Superconducting Na_xCoO_2 + yH_2O Single Crystals Prepared by Electrochemical De-intercalation
F. C. Chou, J. H. Cho, Patrick A. Lee +3
Superconducting single crystal samples of Na_xCoO_2 + yH_2O have been produced using an electrochemical technique which dispenses with the usual bromine chemical de-intercalation s…
Spin dynamics in hole-doped two-dimensional S=1/2 Heisenberg antiferromagnets: ^{63}Cu NQR relaxation in La_{2-x}Sr_xCuO_4 for
P. Carretta, F. Tedoldi, A. Rigamonti +4
The effects on the correlated Cu^{2+} S = 1/2 spin dynamics in the paramagnetic phase of La_{2-x}Sr_xCuO_4 (for ) due to the injection of holes are studied by mean…
