Abstract
The detail experimental study of the domain kinetics in wide field range was carried out in a uniaxial ferroelectric lead germanate Pb 5 Ge 3 O 11 with optically distinguishable 180° domains. The application of the stroboscopic method allows us to realize the in situ study of super-fast domain kinetics during cyclic switching in microsecond range. Three qualitatively distinctive regimes of domain evolution: “slow”, “fast”, and “super-fast” were revealed and domain kinetics was statistically analyzed. The explanation of the observed effects is based on taking into account the variation of the efficiency of the bulk screening of the depolarization field.
