通过观察沿铁电轴的光旋并测量指标绕同一轴的旋转，研究了铁电三甘氨酸硫酸和罗谢尔盐的磁畴切换。实验证实，三甘氨酸硫酸的反极性结构域通过对称孪生机制结合，而罗谢尔盐的反极性结构域通过异斜面（旋转孪生）结合。结果表明，高精度通用旋光计方法可以成为区分铁电畴孪生机制的新通用方法。
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.
