Negative thermal expansion of MgB in the superconducting state and anomalous behavior of the bulk Grüneisen function
J. J. Neumeier, T. Tomita, M. Debessai +4
The thermal expansion coefficient of MgB is revealed to change from positive to negative on cooling through the superconducting transition temperature . The Grüneisen…
Thermal Expansion and Compressibility in Superconducting NaxCoO2o4xD2O (x?1/3): Evidence for Pressure-Induced Charge Redistribution
J. D. Jorgensen, M. Avdeev, D. G. Hinks +2
We have performed thermal expansion and compressibility measurements on the recently discovered superconducting material NaxCoO2*4xD2O (x=1/3) using neutron powder diffraction over…
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…
Epitaxial Thin Films of the Giant-Dielectric-Constant Material CaCu_3Ti_4O_{12} Grown by Pulsed-laser Deposition
W. Si, E. M. Cruz, P. D. Johnson +3
Pulsed-laser deposition has been used to grow epitaxial thin films of the giant-dielectric-constant material CaCu_3Ti_4O_{12} on LaAlO_3 and SrTiO_3 substrates with or without vari…
