摘要：

The domain switching of ferroelectric triglycine sulfuric acid and Rochelle salt was studied by observing optical gyration along the ferroelectric axes and measuring rotation of the indicatrices around the same axes. It was established experimentally that the antipolar domains of triglycine sulfuric acid were united by a symmetric twin mechanism and those of Rochelle salt by a hemitrope (rotation twin). It was shown that the high-accuracy universal polarimeter method can become a new general method for distinguishing the twinning mechanism of the ferroelectric domains.
