Abstract

The temperature dependence of the magnetic properties of magnetic superlattices by using the Bethe approximation to the inhomogeneous Ising model is studied. A self-consistent equation which determines the variation of the magnetic moment for any layer thicknesses is derived. In particular, the crossover from bulk-dominated behavior for large thicknesses of layers to interface-dominated behavior for small thicknesses is discussed. The results both qualitatively and quantitatively differ from mean-field theory; the experimental observation for FeF₂/CoF₂ and CoO/NiO superlattices is explained.
