Observation of an unconventional metal-insulator transition in overdoped CuO_2 compounds

F. Venturini, M. Opel, T. P. Devereaux +7

The electron dynamics in the normal state of BiSrCaCuO is studied by inelastic light scattering over a wide range of doping. A strong anisotropy of the electron…

Pseudogap and Superconducting Gap in Y-123: A Raman Study

Matthias Opel, Martin Götzinger, Christian Hoffmann +6

We present results of electronic Raman-scattering experiments in differently doped Y-123. In B2g symmetry, an analysis of the data in terms of a memory function approach is present…

Physical origin of the buckling in CuO: Electron-phonon coupling and Raman spectra

M. Opel, R. Hackl, T. P. Devereaux +6

It is shown theoretically that the buckling of the CuO planes in certain cuprate systems can be explained in terms of an electric field across the planes which originates fro…

Scaling of the Hall Resistivity in the Solid and Liquid Vortex Phases in Twinned Single Crystal YBCO

G. D'Anna, V. Berseth, L. Forro +2

Longitudinal and Hall voltages are measured in a clean twinned YBCO single crystal in the liquid and solid vortex phases. For magnetic fields tilted away from the c-axis more than…

Origin of the Hall conductivity below the vortex-lattice melting in twinned single crystal YBCO

G. D'Anna, V. Berseth, L. Forro +2

In his the Comment, P. Ao affirms that his vortex many-body theory explains the observations reported in G. D'Anna et al., Phys. Rev. Lett. 81, 2530 (1998). Indeed, we provide here…

Experimental evidence for fast cluster formation of chain oxygen vacancies in YBa2Cu3O7-d being at the origin of the fishtail anomaly

Andreas Erb, Alfred A. Manuel, Marc Dhalle +13

We report on three different and complementary measurements, namely magnetisation measurements, positron annihilation spectroscopy and NMR measurements, which give evidence that th…
