摘要：
We report new data on the electrooptic behaviour of the semiconductor ferroelectric crystal Sn2P2S6 in the temperature region 295-390 K. At the room temperature the magnitude of the effective longitudinal electro-optic coefficient is about 50 pm/V, much larger than the value reported previously. Corresponding half-wave voltage is less than 500V. We also observed Curie-Weiss type increase of r(eff) near the ferroelectric phase transition at 339 K.
