Contribution of spontaneous polarization and its fluctuations to refraction of light in ferroelectrics
Original language description
The expressions for the spontaneous polar contribution δ to the principal values of the refractive index due to the quadratic electro-optic effect in ferroelectrics have been considered within the phenomenological approach taking into account the polarization fluctuations. A method has been proposed for calculating the magnitude and temperature dependence of the root-mean-square fluctuations of the polarization (short-range local polar order) Psh = 〈Pfl2〉1/2 below the ferroelectric transition temperature Tc from temperature changes in the spontaneous polar contribution δnis (Tc) if the average spontaneous polarization Ps = 〈P〉 characterizing the long-range order is determined from independent measurements (for example, from dielectric hysteresis loops).
