Abstract:
The polarization reversal process has been studied in 8mol.\% MgO doped congruent lithium tantalate single crystal using in situ domain visualization and analysis of the switching current data based on original modification of the Kolmogorov-Avrami approach. Two revealed stages of domain structure evolution during cyclic switching representing slow growth of isolated domains and fast motion of macroscopic domain walls were taken into account during analysis of the switching current data. The coercive field for quasi-static switching about 1.2kV/mm was revealed. The main parameters of the switching process have been compared with other representatives of lithium tantalate family.
