On high temperature susceptibilities of Heisenberg model ferromagnetics and anti-ferromagnetics

Abstract

High temperature power series valid for general spin and including second-neighbour interactions are given for the physical susceptibility of the three cubic lattices and for the staggered susceptibility of some antiferromagnetic orderings of the body-centred and face-centred lattices. The critical ordering temperatures corresponding to these series are discussed and compared with the results of molecular field theory.
