Soft and chiral phonons in chiral phase of K3NiO2
Hong Dang Nguyen, Fedir Borodavka, Miroslav Lebeda +6
Raman scattering measurements confirmed the theoretical prediction that the structural phase transition from the achiral tetragonal to the chiral tetragonal phase, which occurs nea…
Suppression of ferromagnetism in van der Waals insulator due to pressure-induced layer stacking variation
M. Misek, U. Dutta, P. Kral +15
Ferromagnetism in van der Waals insulators like CrBr3 is highly sensitive to structural modifications. We explore the pressure-driven structural and magnetic transformations of the…
Dielectric, magnetic and lattice dynamics properties of double perovskite (Ca0.5Mn1.5)MnWO6
Hong Dang Nguyen, Alexei A. Belik, Petr Kužel +7
Recent dielectric and magnetic studies of (Ca0.5Mn1.5)MnWO6 ceramics [A.A. Belik, Chem. Mater. 36, 7604 (2024)] have classified this material as a rare hybrid multiferroic, with bo…
Phonon properties and unconventional heat transfer in quasi-2D crystal
Jan Zich, AntonÃn Sojka, Petr Levinský +10
Bi2O2Se belongs to a group of quasi-2D semiconductors that can replace silicon in future high-speed/low-power electronics. However, the correlation between crystal/band structure a…
Orbital angular momentum impact on light scattering by phonons tested experimentally
A. Pylypets, F. Borodavka, I. Rafalovskyi +4
Polarized Raman spectra of piezoelectric bismuth germanate single crystal were recorded using vortex light in order to verify the predicted symmetry selection rules for Raman scatt…
