Magnetism in ferromagnetic spin-1/2 Ising multilayers

In this work, we study the magnetization profiles of ferromagnetic multilayers consisting of two materials in a sandwich structure (ABA), with ferromagnetic coupling between the films, using an effective field theory with a probability distribution technique that accounts for the self-correlation function. Different exchange interaction terms at the interface are investigated. We present also results on the effect of both the exchange interaction constant in material B and the surface exchange interaction constant on the whole system.
