We study an Ising model in one dimension with short-range ferromagnetic and long-range (power law) antiferromagnetic interactions. We show that the zero temperature phase diagram in a (longitudinal) field H involves a sequence of up and down domains whose size varies continuously with H, between - Hc and Hc, which represent the edges of the ferromagnetic up and down phases. The implications of long-range interaction in many body systems are discussed.
