Evidence of superconductivity-induced phonon spectra renormalization in alkali-doped iron selenides
M. Opačić, N. Lazarević, M. Šćepanović +4
Polarized Raman scattering spectra of superconducting KFeSe and nonsuperconducting KFeCoSe single crystals were measured in a temperatur…
Charge density wave modulation and gap measurements in CeTe
Uros Ralevic, Nenad Lazarevic, Andreas Baum +7
We present a study of charge density wave (CDW) ordering in CeTe at room temperature using a scanning tunneling microscope and Raman spectroscopy. Two characteristic CDW orderi…
Sustained phase separation and spin glass in Co-doped KFeSe single crystals
Hyejin Ryu, Kefeng Wang, M. Opacic +5
We present Co substitution effects in KFeCoSe (0.06 1.73) single crystal alloys. By 3.5\% of Co doping superconductivity is suppressed…
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…
Optical properties of NaxV2O5
M. J. Konstantinovic, Z. V. Popovic, V. V. Moshchalkov +4
The optical properties of sodium-deficient NaxV2O5 (0.85 < x <1) single crystals are analyzed in the wide energy range, from 0.012 to 4.5 eV, using ellipsometry, infrared reflectiv…
Optical studies of gap, hopping energies and the Anderson-Hubbard parameter in the zigzag-chain compound SrCuO2
Z. V. Popovic, V. A. Ivanov, M. J. Konstantinovic +8
We have investigated the electronic structure of the zigzag ladder (chain) compound SrCuO2 combining polarized optical absorption, reflection, photoreflectance and pseudo-dielectri…
