Infrared optical properties of the spin-1/2 quantum magnet
G. Caimi, L. Degiorgi, N. N. Kovaleva +2
We report results on the electrodynamic response of , a low-dimensional spin-1/2 quantum magnet that shows a spin gap formation for T= 67 . The Fano-like shape o…
C-axis lattice dynamics in Bi-based cuprate superconductors
N. N. Kovaleva, A. V. Boris, D. Munzar +8
We present results of a systematic study of the c axis lattice dynamics in single layer Bi2Sr2CuO6 (Bi2201), bilayer Bi2Sr2CaCu2O8 (Bi2212) and trilayer Bi2Sr2Ca2Cu3O10 (Bi2223) cu…
Giant phonon anomalies in the pseudo-gap phase of TiOCl
P. Lemmens, K. Y. Choi, G. Caimi +4
We report infrared and Raman spectroscopy results of the spin-1/2 quantum magnet TiOCl. Giant anomalies are found in the temperature dependence of the phonon spectrum, which hint t…
Anomalous oxygen isotope effect on the in-plane FIR conductivity of detwinned YBa2Cu3O
C. Bernhard, T. Holden, A. V. Boris +6
We observe an anomalous oxygen isotope effect on the a-axis component of the far-infrared electronic response of detwinned YBa2Cu3O. For O a pronounced low…
