Abstract: In this report we present the fabrication of superlattices consisting of heterogeneous magnetic GaAs:MnAs layers and InGaAs spacers with equal thickness. The magnetic and structural properties of such a superlattice are described, showing that under the appropriate annealing conditions the low-temperature grown superlattice structure is preserved and that the MnAs magnetic clusters can be formed in 2D sheets separated by thin (5 - 20 nm) semiconductor layers of good crystalline quality. CPP magnetotransport studies only show measurable MR at low temperatures, dominated by the dilute magnetic semiconductor Ga(Mn)As host lattice of the MnAs clusters.
