Raman and infrared studies of La_1-ySr_yMn_1-xM_xO_3 (M=Cr, Co, Cu, Zn, Sc or Ga): Oxygen disorder and local vibrational modes
A. Dubroka, J. Humlicek, M. V. Abrashev +3
We present results of our study of polarized Raman scattering and infrared reflectivity of rhombohedral ceramic La_1-ySr_yMn_1-xM_xO_3 manganites in the temperature range between 7…

Interpretation of the in-plane infrared response of the high-Tc cuprate superconductors involving spin fluctuations revisited
Petr Casek, Christian Bernhard, Josef Humlicek +1
The in-plane infrared response of the high-Tc cuprate superconductors was studied using the spin-fermion model, where charged quasiparticles of the copper-oxygen planes are coupled…

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…
