[en] Highlights: • Iron/alumina multilayered composites were prepared by the laser ablation technique. • The deposition parameters were varied with the aim of modifying the morphology. • The composites were investigated with the help of SEM, AFM and TEM. • Iron structures consist in either single nanoparticles or continuous interlayers. • Such architectures can be integrated in magnetic devises for information storage. - Abstract: The continuous need of more non-volatile memories with a higher storage capacity, smaller dimensions and weight, as well as lower costs, has led to the exploration of patterned magnetic composites. In this paper, multilayered composites composed of iron nanostructures integrated in an amorphous matrix of alumina were prepared through the laser ablation technique. Further, the deposition parameters were varied with the aim of modifying the morphology of the materials from a continuous matrix containing single metallic particles to a stratified structure with thin metallic interlayers. The resulting composites were investigated with the help of scanning electron microscopy, atomic force microscopy and transmission electron microscopy.
