Neel Temperature for Quasi-Two-Dimensional Dipolar Antiferromagnets

Abstract

We calculate the Néel temperature $T_N$ for two-dimensional isotropic dipolar Heisenberg antiferromagnets via linear spin-wave theory and a high temperature expansion, employing the method of Callen. The theoretical predictions for $T_N$ for K${}_2$MnF${}_4$, Rb${}_2$MnF${}_4$, Rb${}_2$MnCl${}_4$ and (CH${}_3$NH${}_3$)${}_2$MnCl${}_4$ are in good agreement with the measured values.
