In Chapter 2 we considered the magnetism of electrons that may be treated as though they were contained within the cores of atoms in solids. The essential interactions which we expressed as a molecular field are between atoms and the requirement for a paramagnetic or ferromagnetic state was the existence of incompletely filled inner shells of electrons. The paramagnetic susceptibility found in these circumstances varies markedly with temperature, ideally following the Curie Law or the Curie-Weiss Law.
