Resumo: A self-consistent mean field theory is used to study composition effects on the phase transitions of FeF2/CoF2 and FeF2/MnF2 superlattices under weak applied fields. The temperature dependence of the magnetization is shown to depend strongly on the superlattice layering pattern and also on the interface coupling. Thin films of low anisotropy compounds display stronger shifts of transition temperature. Comparison with bulk results shows that size effects persist even for very thick layers for weakly coupled systems.
