Abstract
The concept of “reaction field” introduced by Onsager is applied to the case of a Heisenberg system in the paramagnetic phase. The procedure to obtain the static q‐dependent susceptibility and pair correlation functions is reviewed and extended to calculate the magnetic specific heat. The result of this calculation is compared with experiment.Keywords
