Low-energy interband transitions in the infrared response of Ba(Fe1-xCox)2As2
P. Marsik, C. N. Wang, M. Roessle +8
We studied the doping and temperature (T) dependence of the infrared (IR) response of Ba(Fe1-xCox)2As2 single crystals. We show that a weak band around 1000 cm-1, that was previous…
Angular Dependent Spectral-Weight Transfer and Evidence for Symmetry Broken In-Plane Charge Response in CaNaCuOCl
R. Schuster, S. Pyon, M. Knupfer +4
We report about the energy and momentum dependent charge response in CaNaCuOCl employing electron energy-loss spectroscopy. Along the diagonal of the Brillo…
Macroscopic phase segregation in superconducting K0.73Fe1.67Se2 as seen by muon spin rotation and infrared spectroscopy
C. N. Wang, P. Marsik, R. Schuster +8
Using muon spin rotation (\muSR) and infrared spectroscopy we investigated the recently discovered superconductor K0.73Fe1.67Se2 with Tc = 32 K. We show that the combined data can…
Evidence for Fermi surface reconstruction in the static stripe phase of LaEuSrCuO,
V. B. Zabolotnyy, A. A. Kordyuk, D. S. Inosov +9
We present a photoemission study of LaEuSrCuO with doping level =1/8, where the charge carriers are expected to order forming static stripes. Though…
Optical Study of LaO_0.9F_0.1FeAs: Evidence for a Weakly Coupled Superconducting State
S. -L. Drechsler, M. Grobosch, K. Koepernik +10
We have studied the reflectance of the recently discovered superconductor LaO_0.9F0.FeAs in a wide energy range from the far infrared to the visible regime. We report on the observ…
Excitation energy map of the high-energy dispersion anomalies in cuprates
D. S. Inosov, R. Schuster, A. A. Kordyuk +8
The anomalous high-energy dispersion of the conductance band in the high-Tc superconductor Pb-Bi2212 has been extensively mapped by angle-resolved photoemission (ARPES) as a functi…
