Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | 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 |
