Abstract

It is pointed out that the vanishing of the interface energy at T equals 0 is compatible with the existence of a phase transition at finite temperature in Ising systems. In frustrated systems an interface may cost entropy. This effect may be sufficient to produce a non-zero transition temperature. An explicit example of this behavior is given on a periodic model. Some possible consequences for 2-D Ising spin-glasses are discussed.
