Optical and electric manifestations of incommensurate phase in NH₄HSeO₄ crystals

Andriyevsky, B.V.; Czapla, Z.; Dacko, S.; Myshchyshyn, O.Ya. (Condensed Matter Physics, 1999)

Temperature dependences of the optical path difference by the variable part of refractive index D = (n − 1)l and the components ε′ and ε′′ of complex dielectric permittivity for NH₄HSeO₄ single crystal are studied in ...
Proton ordering model of phase transitions in hydrogen bonded ferrielectric type systems: the GPI crystal

Stasyuk, I.; Czapla, Z.; Dacko, S.; Velychko, O. (Condensed Matter Physics, 2003)

A microscopic model based on the consideration of the proton ordering is proposed for describing the H-bonded ferroelectric crystalline systems with a complex structure of the hydrogen bond network. The model has been used ...
Studying mechanical, acoustical and dielectric properties of SiO₂-filled polyester resin nanocomposites

Gorelov, B.M.; Polovina, O.I.; Gorb, A.M.; Czapla, Z.; Dacko, S. (Functional Materials, 2012)

Concentration effects of fumed silica on mechanical (static Young modulus, compression strength limit), acoustic (Lame constant, shear modulus, Young modulus, compression modulus, and Poisson’s ratio), and dielectric ...
Thermodynamics and dielectric anomalies of DMAAS and DMAGaS crystals in the region of phase transitions (Landau theory approach)

Stasyuk, I.V.; Velychko, O.V.; Czapla, Z.; Czukwinski, R. (Condensed Matter Physics, 2000)

A simple description of thermodynamics of DMAAS and DMAGaS ferroelectric crystals by means of Landau expansion is proposed. Conditions of occurrence of phase transitions are established and their temperatures are obtained. ...
