THE NEEL TEMPERATURE OF MNF2 IN THE TWO-SPIN CLUSTER-VARIATION LIMIT,

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.
