Bsoul I.A. Physical Properties of Li2Ge7O15 Crystals in the Vicinity of
the Phase Transition. Manuscript.

Thesis to obtain a scientific degree of “Candidate of Physico —
Mathematical Sciences” on a speciality 01.04.07. — Solid State Physics,
Dniepropetrovsk State University, Dniepropetrovsk, 1998.

9 scientific works are defended. The main peculiarity of weak
ferroelectrics is the small value of shielding of the spontaneous
polarization field, which results in the increase of role of fluctuation
of the order parameter near OC. It has been found out a strong
temperature hysteresis of dielectric constant for Li2Ge7O15 crystals
near the phase transition temperature which is connected with “freezing”
of the relaxational component of the dielectric constant below TC.
Strong frequency dispersion of max value in frequencies range 103106 Hz
has been established. This dispersion belongs to Debay type. The
temperature behavior of max is connected with the contribution of
lithium sublattice. Critical index of order parameter susceptibility
derived from dielectric measurements is in good agreement with order
parameter critical exponent determined by ESR method. Received data are
in accordance with the three-dimensional Izing model.

Key words: phase transition, dielectric constant, dielectric
hysteresis, weak ferroelectrics, frequency dispersion, critical index.
