Structure and Tc of Y0.8Ca0.2Ba2Cu3O6.92 under High Pressure
Walter H. Fietz, Frank W. Hornung, Kai Grube +4
The lattice parameters and Tc of Y1-yCayBa2Cu3Ox have been determined under pressure up to 10 GPa using a diamond anvil cell. The results are used to test the extended charge trans…

Resonant Raman Study of Superconducting Gap and Electron-Phonon Coupling in YbBa2Cu3O7-delta
S. Ostertun, J. Kiltz, T. Wolf +1
We investigate the electronic background as well as the O2-O3 mode at 330 cm^-1 of highly doped YbBa2Cu3O7-delta in B1g symmetry. Above the critical temperature Tc the spectra cons…
