Antiferromagnetism by the Bethe Method

The Bethe method for order-disorder is applied to a lattice of magnetic dipoles with antiferromagnetic nearest-neighbour interactions. Magnetization and entropy are calculated for all values of temperature and magnetic field, and an anti-parallel ordered phase is found below a definite transition curve The computed curves agree qualitatively with those observed experimentally with certain paramagnetic salts at low temperatures.
