The Rys F model of an antiferroelectric is solved by the transfer-matrix method. The result is different in many respects from the analogous Ising antiferromagnet, i.e., an infinite-order phase transition and a natural boundary in the complex T plane. It can also be solved when an external electric field is included. Above the transition temperature the behavior is normal while below Tc there is no polarization unless the electric field is sufficiently large.
