  • 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 ...
  • Phase diagrams of incommensurate ferroelectric NH₄HSeO₄: phenomenological treatment 
    Kityk, A.V.; Zadorozhna, A.V. (Condensed Matter Physics, 2000)
    The phenomenological analysis of the pressure-temperature (P −T ) phase diagram of NH₄HSeO₄ crystals is presented. It is shown that the disagreement between the experimental results and the theory may be removed assuming ...
