摘要：

The approximation method to obtain the static properties of a system of interacting localized magnetic moments, called “reaction field approximation” (RFA), which is previously used for the paramagnetic phase, is extended to cover the ordered phase of a spin system with Heisenberg interaction. The presence of a small anisotropy is also considered and an application to MnF2 is made. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
