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…
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…
Coexisting polarization mechanisms in ferroelectric uniaxial tetragonal tungsten bronze Ca_0.3Ba_0.7Nb_2O_6
E. Buixaderas, Š. Svirskas, C. Kadlec +6
Using a broad band dielectric spectroscopy approach (1 to 10^14 Hz) we prove that the tungsten bronze Ca0.3Ba0.7Nb2O6 (CBN-30) displays a ferroelectric phase transition of mixed di…
Local structure of relaxor ferroelectric SrBaNbO from pair distribution function analysis
M. Paściak, P. Ondrejkovic, P. Vanek +8
Neutron pair distribution function analysis and first principles calculations have been employed to study short-range correlations in heavily disordered dielectric material SrB…
Multiple soft-mode vibrations of lead zirconate
J. Hlinka, T. Ostapchuk, E. Buixaderas +7
Polarized Raman, IR and time-domain THz spectroscopy of orthorhombic lead zirconate single crystals yielded a comprehensive picture of temperature-dependent quasiharmonic frequenci…
