We use molecular-dynamics simulation to examine the order-disorder behavior in pure ferroelectric KNbO{sub 3} and in KNbO{sub 3}-KTaO{sub 3} ferroelectric-paraelectric solid solutions and superlattices. We find that the order-disorder behavior is remarkably robust and plays an important role in both the polarization rotation associated with switching of the perfect crystal and in the dynamical behavior of the solid solutions and superlattices.
