“…Another reason that comes to mind is a higher-order electrooptical coupling. On the other hand, quite similar nonlinearities are found in the dilatometric studies on TGS and glycine phosphite crystals [4,33] for a comparable temperature region below T C . They are equivalent to a temperature dependence of spontaneous electrostrictive coefficient.…”

“…Single crystals belonging to a family of triglycine sulphate ðNH 2 CH 2 COOHÞ 3 Á H 2 SO 4 , abbreviated hereafter as TGS, are typical representatives of ferroelectrics with hydrogen bonds [1]. Their physical properties have been a subject of extensive studies since 1960's.…”

“…Their physical properties have been a subject of extensive studies since 1960's. Recently, there has been an upsurge in the interest in those materials [2][3][4], including a deuterated TGS isomorph (DTGS). The reasons are a need in comparison of the results for different representatives of the family and the corresponding interest in their thermodynamical behaviour, as well as promising properties of DTGS associated with its pulse repolarization.…”

The birefringence, rotation angle of the optical indicatrix and the gyration along the polar direction are studied in the paraelectric and ferroelectric phases of deuterated triglycine sulphate crystals using the HAUP-type universal null-polarimetric technique. The gyration effect in the multidomain ferroelectric phase is found to be negligibly small, in accordance with the symmetry considerations, while the changes in the birefringence and the indicatrix rotation occurring in the course of the phase transition may be described by electrooptical coupling due to the quadratic spontaneous effect.

Refractive and birefringence indices in the range of transparency of 300 to 700 nm for triglycine sulphate crystals doped with D-serine molecules have been measured in the temperature range of 290 K to 340 K. The obtained optical properties are discussed together with characteristic electrical features of these materials used as pyroelectric sensors for measurement of temperature. The experimental results obtained in this study will be necessary as the reference data for comparison with the calculated refractive indices of TGS + D-serine on the basis of density functional theory. Determination of the proper position of D-serine, will reveal the features of TGS + D-serine crystal structure necessary to achieve stable unipolarity.
