Abstract
Percolation of polarization is considered in solid solutions of incipient ferroelectric KTaO3: Li. The Li impurities were surrounded by a sphere of the interaction radius. The latter was thought to be proportional to the correlation radius, whichcan be represented through the dielectric susceptibility, the temperature dependence of which is well known. This temperature dependence determines the dependence of the average size of the percolative clusters on temperature. It was shown that, in the Hyper-Rayleigh scattering case, the SHG intensity is just proportional to the average size that gives an opportunity to check the idea of existing the percolative clusters by straight comparison of the experimental and theoretical result.
