Fermi Surface Evolution in an Electron-Doped High-Tc Superconductor Revealed by Magnetic Quantum Oscillations
T. Helm, M. V. Kartsovnik, M. Bartkowiak +5
We report on the direct probing of the Fermi surface in the bulk of the electron-doped superconductor NdCeCuO at different doping levels by means of magnetoresistan…
Pair breaking versus symmetry breaking: Origin of the Raman modes in superconducting cuprates
N. Munnikes, B. Muschler, F. Venturini +9
We performed Raman experiments on superconducting (Bi-2212) and (Y-123) single crystals. These results i…
First-Order Type Effects in YBaCuO at the Onset of Superconductivity
L. Tassini, W. Prestel, A. Erb +2
We present results of Raman scattering experiments on tetragonal for doping levels between 0 and 0.07 holes/CuO. Below the o…
Coexistence of metallicity and superconductivity in adjacent bilayers of a high-Tc superconductor
V. B. Zabolotnyy, S. V. Borisenko, A. A. Kordyuk +10
Experimental studies of the electronic structure remain the basic means for understanding the nature of high-temperature superconductivity (HTSC) and testing relevant theoretical m…
Effect of Zn and Ni impurities on the quasiparticle renormalization in Bi-2212
V. B. Zabolotnyy, S. V. Borisenko, A. A. Kordyuk +10
The Cu substitution by Zn and Ni impurities and its influence on the mass renormalization effects in angle resolved photoelectron spectra (ARPES) of Bi-2212 is addressed. We show t…
Diagonal Antiferromagnetic Easy Axis in Lightly Hole Doped Y_{1-x}Ca_xBa_2Cu_3O_6
Andras Janossy, Titusz Feher, Andreas Erb
Hole induced changes in the antiferromagnetic structure of a lightly Ca doped Gd:Y_{1-x}Ca_xBa_2Cu_3O_6 copper oxide single crystal with x~0.008 is investigated by Gd3+ electron sp…
