Abstract
The magnetic order resulting from an indirect exchange between magnetic moments in the metallic phase of a Ga(1-x)Mn(x)As bilayered structure is studied "via" Monte Carlo simulation. The coupling mechanism involves a perturbative calculation in second order of the interaction between the magnetic moments and carriers (holes). We take into account a possible polarization of the hole gas establishing, thus, self-consistency between the magnetic order and the electronic structure. It leads to a ferromagnetic order even in the case of thin layers. This fact is analyzed in terms of the inter- and intra-layer interactions.
