The comparative experimental analysis of polarization reversal kinetics in conventional homogeneous triglycine sulfate (NH2 CH2 COOH)3 ˙ H2SO4; TGS) and relaxor strontium barium niobate (Sr0.61Ba0.39Nb2O6; SBN) crystals have been performed in a broad range of measurement conditions. The experimental data have been collected from microscopic observation of the domain structure, switching current and D-E hysteresis loop registration. The hysteresis loop and dielectric spectra has a strong link to the configuration of ferroelectric microdomains. The domain structure dynamics was examined by the nematic liquid crystal (NLC) method.
