ESR study of (Sr,La,Ca)_{14}Cu_{24}O_{41}
V. Kataev, K. -Y. Choi, M. Grueninger +4
We report an electron spin resonance (ESR) study of single crystals of the spin-chain spin-ladder compound (Sr,La,Ca)_{14}Cu_{24}O_{41}. The data suggest that in intrinsically hole…

C-axis optical properties of high Tc cuprates
D. van der Marel, A. Tsvetkov, M. Grueninger +2
A review is given of the experimental status of the interlayer coupling energy in the cuprates. A second c-axis plasmon is identified in the double layer compound Y123 for various…

Mid-infrared absorption in YBa2Cu3O6: Failure of spin-wave theory in undoped cuprates?
M. Grueninger, D. van der Marel, A. Damascelli +4
The optical conductivity sigma (omega) of undoped YBa2Cu3O6 is studied in detail in the mid-infrared range. Substitutions on all but the Ba site are used to identify the prominent…
