Superconductivity-induced transverse plasma mode and phonon anomaly in the -axis response of the bilayer compound RbCaFeAsF
B. Xu, D. Munzar, A. Dubroka +7
With infrared spectroscopy we studied the out-of-plane (-axis) response of the iron arsenide superconductor ACaFeAsF (A = Rb,Cs) which has a bilayer structure si…
The probability of an encounter of photons in nested and double-nested Mach-Zehnder interferometers
E. Schmidt, A. Dubroka
We present the results of a theoretical work discussing the propagation of an electromagnetic wave through nested Mach-Zehnder interferometers using classical optics and standard q…
Direct observation of double exchange in ferromagnetic LaSrCoO by broadband ellipsometry
P. Friš, D. Munzar, O. Caha +1
We present results of our broadband ellipsometry measurements of the optical response of ferromagnetic LaSrCoO. Our data show that the ferromagnetic transition…
Optical probe of ferroelectric order in bulk and thin film perovskite titanates
M. Rössle, C. N. Wang, P. Marsik +8
We have measured the temperature dependence of the direct band gap, , in SrTiO and BaTiO and related materials with quantum-paraelectric and ferroelectric prope…
Electric-field-induced pyroelectric order and localization of the confined electrons in LaAlO3/SrTiO3 heterostructures
M. Rössle, K. W. Kim, A. Dubroka +13
With infrared ellipsometry, x-ray diffraction, and electric transport measurements we investigated the electric-field-effect on the confined electrons at the LaAlO3/SrTiO3 interfac…
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…
