Dependence of the final state of the magnetization in ferromagnetic bilayers on the magnitude of the super-exchange energy

We study the magnetic behavior of ferromagnetic bilayers and how the super-exchange energy affects it. To this end, we compute, for several values of the super-exchange parameters, the final magnetization states of two configurations of bilayered ferromagnetic domains: one made of two stacked thin square plates and the other made of two stacked thin circular plates. We observe numerically the strong dependance of the final magnetization state with respect to the magnitude of the super-exchange energy.
