Abstract
It was found a non-exponential time dependence of the complex dielectric constant after reducing hydrostatic pressure (p ≲ 1 GPa) at different ferroelectrics with diffuse phase transition. The results show the peculiarity that the dielectric relaxation becomes stronger after a critical time. It is suggested that this effect is connected with localized states responsible for the glasslike properties of these substances.Keywords
