Phonon studies of the phase transition sequence in antiferroelectric single crystal of Pb(Hf0.83Sn0.17)O3
Anirudh K. R., Cosme Milesi-Brault, Christelle Kadlec +5
The sequence of phase transitions in PbHf0.83Sn0.17O3 has been studied by THz, far infrared and Raman spectroscopies, revealing the complementary behaviour of both, polar and non-p…
Phonon properties and unconventional heat transfer in quasi-2D crystal
Jan Zich, Antonín 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…
Infrared, terahertz, and microwave spectroscopy of the soft and central modes in Pb(Mg1/3Nb2/3)O3
D. Nuzhnyy, J. Petzelt, V. Bovtun +4
From the new infrared (IR) reflectivity and time-domain terahertz (THz) spectra combined with available high-frequency dielectric data above the MHz range in a broad temperature ra…
Unusual ferroelectric and magnetic phases in multiferroic 2H-BaMnO ceramics
Stanislav Kamba, Dmitry Nuzhnyy, Maxim Savinov +16
The structural phase transition in hexagonal BaMnO occurring at =130 K was studied in ceramic samples using electron and X-ray diffraction, second harmonic generation as w…
Absence of ferroelectricity in BiMnO3 ceramics
V. Goian, S. Kamba, M. Savinov +4
We performed factor-group analysis of all phonons in possible monoclinic C2/c and C2 structures of BiMnO3 and compared it with our experimental infrared and Raman spectra. We concl…
Polar phonon anomalies in single crystalline TbScO3
Stanislav Kamba, Veronica Goian, Dmitry Nuzhnyy +6
Polarized infrared reflectivity spectra of a (110)-oriented TbScO3 single crystal plate were measured down to 10 K. The number of observed polar phonons active along the crystallog…
