Abstract :
The interfacial mixing phenomenon for Fe-Al magnetic thin-film system was quantitatively investigated using molecular dynamics simulation. The Fe-Al system has shown different characteristics such as layer coverage function and mixing length, compared with other ferromagnetic/nonferromagnetic metallic bilayer systems. The different intermixing behavior could be successfully explained in terms of cohesive energy and local acceleration effect. In addition, it can be clearly seen that intermixing was rather insensitive to changes in the adatom kinetic energy but dependent on the substrate temperature.
