Abstract

The interfacial feature and growth morphology of a Fe-Al metallic bilayer system were quantitatively investigated by molecular dynamics simulation. Fe atoms of 0.1 eV incident energy were deposited on an Al (001) substrate at 300 K. At the interface region, an intermetallic compound was formed and found to be of the B2 structure. However, the Fe/Al system showed different characteristics, such as a layer coverage function and a mixing length, in comparison with other ferromagnetic/nonferromagnetic metallic bilayer systems. The different intermixing behaviors were successfully explained in terms of cohesive energy and lattice matching.
