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…
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…
Exciton doublet in the Mott-Hubbard LiCuVO insulator identified by spectral ellipsometry
Y. Matiks, P. Horsch, R. K. Kremer +2
Spectroscopic ellipsometry was used to study the dielectric function of LiCuVO, a compound comprised of chains of edge-sharing CuO plaquettes, in the spectral range (0.75…
