Superconductivity and Cobalt Oxidation State in Metastable Na(x)CoO(2-delta)*yH2O (x ~ 1/3; y ~ 4x)
P. W. Barnes, M. Avdeev, J. D. Jorgensen +3
We report the synthesis and superconducting properties of a metastable form of the known superconductor NaxCoO2*yH2O (x ~ 1/3, y ~ 4x). Instead of using the conventional bromine-ac…

Temperature dependent total scattering structural study of CaCu3Ti4O12
E. S. Bozin, V. Petkov, P. W. Barnes +4
X-ray and neutron powder diffraction data as a function of temperature are analyzed for the colossal dielectric constant material CaCu3Ti4O12. The local structure is studied using…
