Abstract :
The electrical and optical properties of lead titanate (PbTiO3) at room temperature are theoretically investigated by using a microscopic model based on the orbital approximation in correlation with the dipole-dipole interaction. We find that both the first-, second-, and third-order electronic polarizabilities have to be considered in this calculation in order to match both the spontaneous polarization and refractive indices with experimental data.
