Cím:	Grain Boundary Diffusion Dominated Mixing and Solid State Reactions in Magnetic Thin Films / Gábor L. Katona, Szilvia Gulyas
Dátum:	2020
Megjegyzések:	Magnetic thin films with L10 ordered structure usually exhibit high magnetocrystalline anisotropy, reasonable coercivity, saturation magnetization, excellent corrosion resistance. Examples for such systems are Fe-Pt, Co-Pt, Fe-Pd, Fe-Ni. The ordered phases are almost exclusively fabricated by employing high temperature annealing or deposition on heated substrates, because of the activation of the necessary diffusion processes. At lower temperatures bulk diffusion slows down and becomes practically negligible, while diffusion along defects, like grain boundaries and dislocations is still available. During grain boundary interdiffusion the migration of the boundary can happen, and the migrating boundary leaves an alloyed zone behind. This phenomenon is called diffusion induced grain boundary migration (DIGM), and can lead to even full intermixing if the grain size is small enough. Here, after a short introduction of this process, examples of ordered phase formation at low temperatures in magnetic thin films will be reviewed.
