Abstract:

A new one-dimensional antiferromagnetic Ising model with exponential pair interactions is proposed. This model is composed of 2N Ising spins, half of which belong to an α-sublattice and the others to a β-sublattice. The interaction between spins in the same sublattice is long-rang ferromagnetic and that between spins in the different sublattices is long-rang antiferromagnetic. Thermodynamic properties of the model are shown to be the same as those obtained by using the molecular field theory for the Ising model with nearest-neighbor interactions.
