Abstract
Abstract A detailed optical activity studies of single crystals of TGS and DTGS with various deuterations in spectral range from 457,9 nm to 632,8 nm at a temperature of 293 K using a sensitive modulation technique have been carried out. Temperature dependences of the optical rotatory power ρ have been measured and linear relation between ρ and spontaneous polarization Ps has been found for both crystals. Similar relation has been given by Hermelbracht and Unruh [1] and Vlokh et al. [2] for TGS crystal. The reversibility of the rotatory power has been found by inspection of Airy spirals when ferroelectric domains are switched. Symetric and unipolar electrogiration hysteresis loops, connected with ferroelectric hysteresis loops have been observed in TGS and DTGS crystals during repolarization of domains.
