We show that there exists a novel long range interaction in ferroelectric Sm-C* materials due to thermally excited polarization waves. We propose that this interaction is the long range repulsion whose existence had been postulated earlier to explain the long period ferrielectric phases observed near the ferroelectric to antiferroelectric phase transition.
