Conference Paper Description

Because a given spin polarizes its neighbourhood, the mean field it feels may be separated into an Onsager cavity field and a local anisotropy due to the random freezing of neighbours as T yields 0. Such a combination may produce several equilibrium positions, thus restoring an Ising picture out of a Heisenberg model. The effects on spin susceptibility and specific heat are briefly discussed, taking into account the quantum nature of spins.
