• We have obtained soliton solutions in the optical and acoustic branches by considering the long wavelength or continuum limit of diatomic lattices in three nonlinear potential regimes: cubic, both cubic and quartic, as well as fourth and sixth order nonlinearity in the nearest neighbour interactions. In the first two cases we get in the acoustic region KdV-type solitons and in the optical region nonlinear Schrodinger type amplitude modulated envelope solitons, where as in the later case we get MKdV-type acoustic solitons and tanh-kink-antikink optical solitons. These tanh-kink solitary waves can be used to account for the structural phase transition in perovskite ferroelectrics.
