Abstract
The Rys F model of hydrogen-bonded antiferroelectrics is generalized to include all ionized vertices. For a class of realistic choices of energy parameters, it is shown that this model is equivalent to a two-dimensional Ising model and consequently exhibits a logarithmically second-order phase transition.
