Description
The microcanonical entropy s(e,m) as a function of energy e and magnetization m is computed analytically for the anisotropic Heisenberg model with Curie-Weiss-type interactions for anti-ferromagnetic and ferromagnetic cases. The results show non-equivalence of ensembles for certain cases and thermodynamic equivalence to the Ising and Heisenberg models in other cases.
