TEMPERATURE DEPENDENCE OF THE ANTIFERROMAGNETIC ANISOTROPY IN MNF2,

Abstract

Existing data on the temperature dependence of the sublattice magnetization and of the antiferromagnetic resonance frequency of MnF2, together with new antiferromagnetic resonance data, are used to determine the temperature dependence of the antiferromagnetic anisotropy energy. The experimental results are discussed in terms of the existing theoretical treatments of this problem, particularly the classical theory of Zener, and the spin-wave theory of Oguchi. Considerations indicate the existence of nearly complete correlation between neighboring spins at all temperatures right up to the Neel temperature. (Author)
