Abstract: By means of the generalized Ginzburg-Landau-Devoshire (GLD) theory , the influence of the interface between two different materials with the second order transition on the properties of ferroelectric thin films with the step-type and slowly varying structures is studied.

Key words: ferroelectric thin film, GLD theory, free energy, ferroelectric phase transition
