Lattice dynamics and electronic excitations in a large family of lacunar spinels with a breathing pyrochlore lattice structure
S. Reschke, F. Meggle, F. Mayr +6
Reproducing the electronic structure of AMX lacunar spinels with a breathing pyrochlore lattice is a great theoretical challenge due to the interplay of various factors. Th…
Optical spectroscopy on the photo-response in multiferroic BiFeO at high pressure
F. Meggle, J. Ebad-Allah, J. Kreisel +1
The pressure dependence of light-induced effects in single-crystalline BiFeO is studied by optical spectroscopy. At low pressures, we observe three light-induced absorption fea…
Infrared spectroscopy study of the nodal-line semimetal candidate ZrSiTe under pressure: Hints for pressure-induced phase transitions
J. Ebad-Allah, M. Krottenmüller, J. Hu +3
We studied the effect of external pressure on the optical response of the nodal-line semimetal candidate ZrSiTe by reflectivity measurements. At pressures of a few GPa, the reflect…
Optical signature of the pressure-induced dimerization in the honeycomb iridate -LiIrO
V. Hermann, J. Ebad-Allah, F. Freund +4
We studied the effect of external pressure on the electrodynamic properties of -LiIrO single crystals in the frequency range of the phonon modes and the Ir - trans…
Pressure-induced formation of rhodium zigzag chains in the honeycomb rhodate LiRhO
V. Hermann, S. Biswas, J. Ebad-Allah +8
We use powder x-ray diffraction to study the effect of pressure on the crystal structure of the honeycomb rhodate LiRhO. We observe low-pressure ( = 6.5 GPa)…
Temperature-dependent photo-response in multiferroic BiFeO revealed by transmission measurements
F. Meggle, M. Viret, J. Kreisel +1
We studied the light-induced effects in BiFeO single crystals as a function of temperature by means of optical spectroscopy. Here we report the observation of several light-ind…
