Abstract
Switching kinetics has been compared in congruent (CLT) and stoichiometric (SLT) lithium tantalate by simultaneous recording of instantaneous domain p atterns and switching current. A mechanism of fast domain kinetics in CLT d riven by domain merging was revealed. The important information about the d omain kinetics has been obtained by the statistical analysis of current noi se in SLT. A model of jerky domain wall motion is proposed.
