Journal ArticleDOI
Preparation, structure, and properties of the superconducting compound series Bi 2 Sr 2 Ca n-1 Cu n O y with n=1, 2, and 3
J. M. Tarascon,W. R. McKinnon,Philippe Barboux,D. M. Hwang,B. G. Bagley,Laura Greene,G. W. Hull,Y. LePage,N. G. Stoffel,M. Giroud +9 more
TL;DR: Transmission electron microscopy shows there are stacking faults within the crystals in agreement with the x-ray data and its analysis, and Resistivity, ac susceptibility and dc magnetization measurements demonstrate superconductivity in the n = 1, 2, and 3 phases at 10, 85, and 110 K respectively.
Journal ArticleDOI
Bismuth cuprate high-Tc superconductors using cationic substitution.
J. M. Tarascon,Philippe Barboux,G. W. Hull,R. Ramesh,Laura Greene,M. Giroud,M. S. Hegde,W. R. McKinnon +7 more
TL;DR: In this article, the structural and physical properties of rare-earth elements were studied to determine their structural properties, and the authors found that for most of the rare earth elements, a complete solid solution exists up to x=2.
Journal ArticleDOI
Determination of dopant site occupancies in Cu-substituted YBa2Cu3O7- delta by differential anomalous x-ray scattering.
R. S. Howland,Theodore H. Geballe,S. S. Laderman,A. Fischer-Colbrie,Michael Paul Scott,Jean-Marie Tarascon,Philippe Barboux +6 more
TL;DR: In all cases, the results appear to have high statistical significance, with very little sensitivity to expected uncertainties in oxygen content, total dopant content, anomalous corrections to the atomic scattering factor of the dopant, and to relative atomic coordinates assumed in the modeling.
Journal ArticleDOI
Oxygen-deficiency-induced localized optical excitations in YBa2Cu
TL;DR: Two strong electronic transitions in the visible--near-uv optical spectra of YBa/sub 2/Cu/sub 3/O/sub x/ that are activated by oxygen deficiency are reported, emphasizing the importance of specific localization and correlation effects in the oxygen dependence of the electronic structure in this compound.
Journal ArticleDOI
Optical properties of copper-oxygen planes in superconducting oxides and related materials
TL;DR: By comparing the spectra of many materials containing similar Cu-O structures, it is determined that some of the optical features are associated with specific local structures within the unit cell.
