The model of static charged clusters, which adequately describes the dielectric hysteresis and permittivity of disordered ferroelectrics with non-isovalent impurities, has been proposed. The main result of paper is modified ...

In the paper we theoretically consider the dynamics of the inner field and the spatial-temporal features of periodical photoinduced light scattering in photo-ferroelectrics caused by stationary laser illumination. Not only ...
