Phase separation and phase transitions in undoped and Rh3+ doped iron pnictide CaFe2As2: a Raman scattering study
V. P. Gnezdilov, A. Yu. Glamazda, P. Lemmens +2
Iron-pnictides Ca(Fe1-xRhx)2As2 (x = 0, 0.035, and 0.19) were studied across the tetragonal-orthorhombic and uncollapsed to collapsed tetragonal phase transitions using Raman spect…
Raman scattering of plane-wave and twisted light off chiral molecular liquids
Florian Büscher, Silvia Müllner, Dirk Wulferding +5
We present an experimental study of the quasi-elastic Raman scattering (QES) of plane-wave and twisted light by liquid crystals. Depending on their temperature, these crystals can…
Flat-band spin dynamics and phonon anomalies of the saw-tooth spin-chain system FeO(SeO)
V. P. Gnezdilov, Yu. G. Pashkevich, V. S. Kurnosov +11
Fe ions form saw-tooth like chains along the axis of the oxo-selenite FeO(SeO) and an onset of long-range magnetic order is observed for temperatur…
Optical phonon dynamics and electronic fluctuations in the Dirac semimetal Cd3As2
A. Sharafeev, V. Gnezdilov, R. Sankar +2
Raman scattering in the three-dimensional Dirac semimetal Cd3As2 shows an intricate interplay of electronic and phonon degrees of freedom. We observe resonant phonon scattering due…
Phase separation in iron chalcogenide superconductor Rb0.8+xFe1.6+ySe2 as seen by Raman light scattering and band structure calculations
Yu. Pashkevich, V. Gnezdilov, P. Lemmens +7
We report Raman light scattering in the phase separated superconducting single crystal Rb0.77Fe1.61Se2 with Tc = 32 K. The spectra have been measured in a wide temperature range 3K…
Electronic structure and magnetic properties of FeTe, BiFeO, SrFeO and SrCoTiFeO compounds
G. E. Grechnev, A. A. Lyogenkaya, O. V. Kotlyar +2
The electronic energy structures and magnetic properties of iron-based compounds with group VI elements (FeTe, BiFeO, SrFeO and SrCoTiFeO) are studi…
