Electronic structure and electron energy-loss spectra of Sr0.35CoO2
R. J. Xiao, H. X. Yang, L. F. Xu +3
The electronic structure of Sr0.35CoO2, structurally analogous to the layered NaxCoO2, has been evaluated using the local spin density approximation (LSDA). We find that evident c-…
Correlations among superconductivity, structural instability, and band filling in Nb1-xB2 at the critical point x=0.2
R. J. Xiao, K. Q. Li, H. X. Yang +5
We performed an extensive investigation on the correlations among superconductivity, structural instability and band filling in Nb1-xB2 materials. Structural measurements reveal th…
Electron energy loss spectra of Na0.33CoO2.yH2O (y = 0, 0.6 and 1.3)
J. Q. Li, H. X. Yang, R. J. Xiao +2
Electron energy loss (EEL) spectra have been obtained on materials with the nominal compositions of Na0.33CoO2_yH2O (y = 0, 0.6 and 1.3). Spectral analyses revealed systematic chan…
Phase separation, effects of magnetic field and high pressure on charge ordering in y-Na0.5CoO2
H. X. Yang, Y. G. Shi, C. J. Nie +7
Transmission electron microscopy observations reveal the presence of complex superstructures and remarkable phase separation in association with Na-ordering phenomenon in y-Na0.5Co…
Structure and physical properties of NaxCoO2.yH2O superconducting system
Y. G. Shi, J. Q. Li, H. C. Yu +3
The structural properties of NaxCoO2 and NaxCoO2yH2O have been investigated. The NaxCoO2yH2O samples in general show up the superconducting transitions at around 3.5K. EDAX analyse…
