摘要

摘要在热力学理论框架内，提出了一种确定电光系数的方法。研究表明，对于所有对称性铁电体来说，只要其存在对角线感度，某些电光系数的比值就可以用感度的比值来表示。对于钛酸钡，我们揭示并研究了电光系数与电场的关系。研究表明，钛酸钡电光系数的较大值与介电感应强度对电场的非线性依赖有关。

Determination of the Electro-Optical Coefficients of Barium Titanate

Within the framework of the theory of thermodynamics, a method for determining the electro-optical coefficients is proposed. It is shown that for all ferroelectrics the symmetry of which admits a diagonal susceptibility, the ratio of some electro-optical coefficients is expressed in terms of the ratio of susceptibilities. For barium titanate, the dependence of the electrooptical coefficients on the electric field has been revealed and studied. It is shown that large values of the electro-optical coefficients of barium titanate are associated with a nonlinear dependence of the dielectric susceptibility on the electric field.
