Bipartite Lattice

A bipartite lattice is a lattice with 2 sublattices, so that each spin on sublattice A interacts only with some spin on the other sublattice B.

Antiferromagnetic State

Each sublattice assumes a uniform magnetization.

The classical Ising antiferromagnet on this lattice is given by the Hamiltonian:
