Abstract:

The Neel temperature of MnF2 was calculated by application of the Cluster-Variation method in the two-spin limit. By treating the anisotropy energy as a quantity comparable to the exchange energy as indicated by experiment a considerable improvement over the molecular field value is obtained for T sub N. Author
