  • Description of lattice anharmonicity observed in ferroelectrics with unusual three-well local potential 
    Yevych, R.; Vysochanskii, Yu. (Condensed Matter Physics, 2018)
    For Sn₂P₂S₆ family of uniaxial ferroelectrics, the anharmonic quantum oscillators model, based on local threewell potential for spontaneous polarization fluctuations, has been used for a description of anharmonic properties, ...
  • Dipole models of proper ferroelectrics NaNO₂ and Sn(Pb)₂P₂S(Se)₆ 
    Drobnich, A.; Vysochanskii, Yu. (Condensed Matter Physics, 1998)
    На прикладi кристалу NaNO₂ аналiзуються ізінгівські дипольні моделi сегнетоелектричних кристалів з введенням локального поля макровзiрця i без нього. Нами розроблена iзінгiвська дипольна модель сегнетоелектрикiв сiм’ї ...
  • Nonlinear dynamics of ferroelectrics with three-well local potential 
    Yevych, R.; Medulych, M.; Vysochanskii, Yu. (Condensed Matter Physics, 2018)
    For Sn₂P₂S₆ ferroelectrics, the appearance of spontaneous polarization is related to stereoactivity of tin cations and valence fluctuations of phosphorous cations. Here, the continuous phase transition and its behavior ...
  • The phase transitions character and microscopic models for Sn₂P₂S(Se)₆ ferroelectrics 
    Vysochanskii, Yu.; Drobnich, A. (Condensed Matter Physics, 2002)
    The paper considers an example of concrete objects, i.e. ferroelectrics of Sn₂P₂S₆ family, for which, according to general estimations, a correlation between the shape of a phase diagram (the presence of a Lifshitz ...
  • Valence fluctuations in Sn(Pb)₂P₂S₆ ferroelectrics 
    Yevych, R.; Haborets, V.; Medulych, M.; Molnar, A.; Kohutych, A.; Dziaugys, A.; Banys, Ju.; Vysochanskii, Yu. (Физика низких температур, 2016)
    The valence fluctuations which are related to the charge disproportionation of phosphorous ions P⁴⁺+P⁴⁺→P³⁺+P⁺⁵ are the origin of ferroelectric and quantum paraelectric states in Sn(Pb)₂P₂S₆ semiconductors. They involve ...
