Abstract:

The influence of macroscopic particles (5—30 μт) BaTiO[3], inclusions on the ferroelectric properties of TGS polycrystalline samples are presented, it is shown that the effect of the interaction increases the temperature of the TGS ferroelectric phase transition during heating. The results obtained are discussed within the context of Ginzburg — Landau theory taking into account the dipole-dipole interaction.
