Optical anisotropy of the Jeff = 1/2 Mott insulator Sr2IrO4
D. Pröpper, A. N. Yaresko, M. Höppner +7
We report the complex dielectric function along and perpendicular to the IrO2 planes in the layered perovskite Sr2IrO4 determined by spectroscopic ellipsometry in the spectral rang…
Doping-Dependent Raman Resonance in the Model High-Temperature Superconductor HgBa2CuO4+d
Yuan Li, M. Le Tacon, Y. Matiks +11
We study the model high-temperature superconductor HgBa2CuO4+d with electronic Raman scattering and optical ellipsometry over a wide doping range. The resonant Raman condition whic…
Dimensionality Control of Electronic Phase Transitions in Nickel-Oxide Superlattices
A. V. Boris, Y. Matiks, E. Benckiser +15
The competition between collective quantum phases in materials with strongly correlated electrons depends sensitively on the dimensionality of the electron system, which is difficu…
Anisotropic optical response of the mixed-valent Mott-Hubbard insulator NaCu2O2
Y. Matiks, A. N. Yaresko, K. Myung-Whun +4
We report the results of a comprehensive spectroscopic ellipsometry study of NaCu2O2, a compound composed of chains of edge-sharing Cu2+O4 plaquettes and planes of Cu1+ ions in a O…
Eliashberg approach to superconductivity-induced infrared anomalies in Ba0.68K0.32Fe2As2
A. Charnukha, O. V. Dolgov, A. A. Golubov +5
We report the full complex dielectric function of high-purity single crystals with …
Superconductivity-induced optical anomaly in an iron arsenide
A. Charnukha, P. Popovich, Y. Matiks +5
One of the central tenets of conventional theories of superconductivity, including most models proposed for the recently discovered iron-pnictide superconductors, is the notion tha…
