Abstract: | The experimental investigation of pyroelectric and polarization properties of TGS crystals was made. TGS crystals were grown under constant growth conditions (temperature and supersaturation of the solution) and γ-irradiated in a wide range of irradiation. The influence of γ-irradiation on the quality parameter M2 of crystals, on the form of hysteresis loops, on size of spontaneous polarization and shifting field was ascertained. |
