The electromagnetic behavior of nano-scale layered and particulate structures of Fe@sub x@Al@sub 1-x@N materials have potential applications in medical device technologies. Iron and aluminum have been co-sputtered in an Ar-N@sub 2@ ambient to form a combinatorial array of Fe@sub x@Al@sub 1-x@N thin films. Using this approach, we are able to achieve an Fe/(Fe+Al) cation range from ~ 12-60 % over 10 cm long substrate. The deposited films were annealed in vacuum at various temperatures and the films have been characterized by x-ray photoelectron spectroscopy, energy dispersive x-ray spectroscopy, scanning electron microscopy and x-ray diffraction. Furthermore, the ac and dc magnetic properties of the films have been characterized. In this presentation, we will describe in detail the reactive combinatorial Fe@sub x@Al@sub 1-x@N sputtering approach. The chemical, structural, and morphological properties as a function of Fe/(Fe+Al) content will be demonstrated and correlated to the measured dc and ac magnetic properties. *This work was sponsored by Biophan Technologies.
