  • Lattice dynamics of a monoclinic CsH₂PO₄ crystal 
    Shchur, Ya.I.; Levitskii, R.R.; Vlokh, O.G.; Kityk, A.V.; Vysochansky, Y.M.; Grabar, A.A. (Condensed Matter Physics, 1999)
    The phonon dispersion relations in a CsH₂PO₄ crystal in a paraelectric phase by means of a rigid molecular-ion model are calculated. The phonon spectra in the quasi-harmonic approximation at various values of temperature ...
  • Temperature dependence of the Brillouin spectra in Sn₂P₂S(Se)₆ ferroelectric crystals 
    Yevych, R.M.; Perechinskii, S.I.; Grabar, A.A.; Vysochanskii, Yu.M.; Slivka, V.Yu. (Condensed Matter Physics, 2003)
    A temperature dependence of hypersound velocities at transition from a paraelectric phase to ferroelectric phase in Sn₂P₂S₆ crystals was investigated by Brillouin scattering spectroscopy. Based on these data, full set ...
