Abstract
We discuss in one as well as three dimensions an antiferromagnetic model with Neel states as ground states. Long-range order exists for this Hamiltonian. Finite-temperature properties of this Hamiltonian can be computed through the usual Green-function method and the results obtained are identical with those of the isotropic Heisenberg Hamiltonian through a similar method. The reason for this identity and its implication in analysis of experimental data are discussed.
