TEMPERATURE DEPENDENCE OF THE BRILLOUIN SPECTRA IN Sn<sub>2</sub>P<sub>2</sub>S(Se)<sub>6</sub> FERROELECTRIC CRYSTALS

TEMPERATURE DEPENDENCE OF THE BRILLOUIN SPECTRA IN Sn<sub>2</sub>P<sub>2</sub>S(Se)<sub>6</sub> FERROELECTRIC CRYSTALS

A temperature dependence of hypersound velocities at transition from a paraelectric phase to ferroelectric phase in Sn<sub>2</sub>P<sub>2</sub>S<sub>6</sub> crystals was investigated by Brillouin scattering spectroscopy. Based on these data, full set of elastic co...
