Collective density wave excitations in two-leg Sr_{14-x}Ca_xCu_{24}O_{41} ladders
A. Gozar, G. Blumberg, P. B. Littlewood +4
Raman measurements in the 1.5 - 20 cm-1 energy range were performed on single crystals of Sr_{14-x}Ca_xCu_{24}O_{41}. A quasielastic scattering peak (QEP) which softens with coolin…
Spin dynamics of Sr_14Cu_24O_41 two-leg ladder studied by Raman spectroscopy
A. Gozar, G. Blumberg, B. S. Dennis +4
The two-magnon (2M) excitation at 3000 cm-1 in Sr_14Cu_24O_41 two-leg ladder is studied by Raman scattering. A slight anisotropy of the superexchange coupling J_{\perp}/J_{||} \app…
Hole distribution for (Sr,Ca,Y,La)_14 Cu_24 O_41 ladder compounds studied by x-ray absorption spectroscopy
N. Nücker, M. Merz, C. A. Kuntscher +20
The unoccupied electronic structure for the Sr_14Cu_24O_41 family of two-leg ladder compounds was investigated for different partial substitutions of Sr^2+ by Ca^2+, leaving the no…
The dynamics of a hole in a CuO_4 plaquette: electron energy-loss spectroscopy of Li_2CuO_2
S. Atzkern, M. Knupfer, M. S. Golden +7
We have measured the energy and momentum dependent loss function of Li_2CuO_2 single crystals by means of electron energy-loss spectroscopy in transmission. Using the same values f…
