%X The phase transition characteristics of ferroelectric films with domain structure were studied using Landau free energy expansion. The existence of domain walls reduces both the spontaneous polarization and the Curie temperature, and increases the critical size. The reversal length moves away from the surfaces as temperature increases. As the film becomes thinner, the film will turn into single domain.
