摘要：

The microscopic mechanism of refractive indices, birefringence and spontaneous polarization of BaTiO3 at room temperature is discussed by using a microscopic model. In this model, we have taken into account a quantum method based upon the orbital approximation and the dipole-dipole interaction due to the local field acting on the constituent ions. It is found that the electronic polarizabilities play a major role in these calculations.
