Ferroelectric domain inversion in KTiOPO4 crystals has been studied for two different states of these crystals: superionic (at room temperature), and dielectric (at low temperature, when the ion transport is frozen). The structure of the ferroelectric domain inverted at room temperature demonstrates a dramatic domain broadening due to a bulk domain nucleation. The observed effect is ascribed to highly mobile potassium ions that contribute to the minimization of the depolarizing field and the surface energy of domain walls of new domain nuclei.
