Polarization-dependent infrared reflectivity study of SrCaCuO under pressure: Charge dynamics, charge distribution, and anisotropy
S. Frank, A. Huber, U. Ammerahl +2
We present a polarization-dependent infrared reflectivity study of the spin-ladder compound SrCaCuO under pressure. The optical response is strongly…
Structural transitions in a doped lanthanum cuprate
S. -H. Baek, P. C. Hammel, M. Hücker +4
139La NMR and relaxation measurements have been performed on La{1.8-x}Eu{0.2}Sr{x}CuO{4} (x = 0.13 and 0.2) single crystals. The temperature dependence of the 139La NMR spectra in…
Plasmons and Interband Transitions of CaSrCuO investigated by Electron Energy-Loss Spectroscopy
Friedrich Roth, Christian Hess, Bernd Büchner +3
Electron energy-loss spectroscopy studies have been performed in order to get a deeper insight into the electronic structure and elementary excitations of the two-leg ladder system…
Nernst Effect of stripe ordering LaEuSrCuO
Christian Hess, Emad M. Ahmed, Udo Ammerahl +2
We investigate the transport properties of LaEuSrCuO (, 0.08, 0.125, 0.15, 0.2) with a special focus on the Nernst effect in the normal state. Var…
Dynamical spin chirality and spin anisotropy in gapped S=1/2 quantum systems
J. E. Lorenzo, C. Boullier, L. P. Regnault +2
We have studied the spin anisotropy in spin-singlet ground state compounds and the magnetic chirality, as measured by inelastic polarized neutron scattering techniques, in the chai…
Charge density waves in Sr_14-xCa_xCu_24O_41: electron correlations vs. structural effects
K. -Y. Choi, M. Grove, P. Lemmens +7
We report inelastic light scattering experiments in the spin-chain and ladder system Sr_14-xCa_xCu_24O_41. A depletion of an electronic background is observed for 0 < x < 5 at low…
