Theory of Surface-Induced Magnetism in Adsorbed 3He Films. II: Curie-Weiss Temperature (Reinvestigated), Curie Constant and Liquid-Layer Susceptibility

Within a three-layer model, previously proposed by the author, the Curie-Weiss temperature of adsorbed 3He films is reinvestigated by taking all exchange constants into account, and the Curie constant and liquid-layer susceptibility are calculated. Better agreement with the experiment by Franco et al. is obtained for the coverage-dependence of the Curie-Weiss temperature. It is also found that 1) the Curie constant is almost independent of the density of liquid-layer atoms and 2) the susceptibility of two liquid layers is negligible at low temperatures compared with that of the solid layer.
