Influence of electric fields on dielectric properties of GPI ferroelectric
Using modified microscopic model of GPI by taking into account the piezoelectric coupling with strains εi in the frames of two-particle cluster approximation, the components of polarization vector and static dielectric permittivity tensor of the crystal at applying the external transverse electri...

Вплив електричних полiв на дiелектричнi властивостi сегнетоелектрика GPI |
| description |
Using modified microscopic model of GPI by taking into account the piezoelectric coupling with strains εi
in
the frames of two-particle cluster approximation, the components of polarization vector and static dielectric
permittivity tensor of the crystal at applying the external transverse electric fields E₁ and E₃ are calculated. An
analysis of the influence of these fields on thermodynamic characteristics of GPI is carried out. A satisfactory
quantitative description of the available experimental data for these characteristics has been obtained at a
proper choice of the model parameters
Використовуючи модель GPI, модифiковану шляхом врахування п’єзоелектричного зв’язку з деформацiями εi в наближеннi двочастинкового кластера, розраховано компоненти вектора поляризацiї та тензора
статичної дiелектричної проникностi кристала при прикладаннi зовнiшнiх поперечних електричних полiв E₁ i E₃. Проведено аналiз впливу цих полiв на дiелектричнi характеристики GPI. При належному
виборi параметрiв теорiї отримано задовiльний кiлькiсний опис наявних експериментальних даних для
цих характеристик.
