Infrared ellipsometry study of the photo-generated charge carriers at the (001) and (110) surfaces of SrTiO crystals and the interface of corresponding LaAlO/SrTiO heterostructures
M. Yazdi-Rizi, P. Marsik, B. P. P. Mallett +7
With infrared (IR) ellipsometry and DC resistance measurements we investigated the photo-doping at the (001) and (110) surfaces of SrTiO (STO) single crystals and at the corres…
Infrared ellipsometry study of the confined electrons in a high-mobility -AlO/SrTiO heterostructure
Meghdad Yazdi-Rizi, Premysl Marsik, Benjamin Mallett +5
With infrared ellipsometry we studied the response of the confined electrons in a -AlO/SrTiO heterostructures in which they originate predominantly from oxygen vacan…
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…
Optical identification of hybrid magnetic and electric excitations in Dy3Fe5O12 garnet
P. D. Rogers, Y. J. Choi, E. Standard +10
Far-infrared spectra of magneto-dielectric Dy3Fe5O12 garnet were studied between 13 and 100 cm-1 and at low temperatures between 5 and 80 K. A combination of transmission, reflecti…
Coexistence and competition of magnetism and superconductivity on the nanometer scale in underdoped BaFe1.89Co0.11As2
P. Marsik, K. W. Kim, A. Dubroka +9
We report muon spin rotation (muSR) and infrared (IR) spectroscopy experiments on underdoped BaFe1.89Co0.11As2 which show that bulk magnetism and superconductivity (SC) coexist and…
Evidence for multiple superconducting gaps in optimally doped BaFeCoAs from infrared spectroscopy
K. W. Kim, M. Rössle, A. Dubroka +3
We performed combined infrared reflection and ellipsometry measurements of the in-plane optical reponse of single crystals of the pnictide high temperature superconductor BaFe$_{1.…
