Impact of Fe${}_{80}$B${}_{20}$ insertion on the properties of dual-MgO perpendicular magnetic tunnel junctions

Enlong Liu, Taeyoung Lee, Hyunsoo Yang

We explore the impact of Fe80B20 inserted at both Co${}_{20}$Fe${}_{80}$B${}_{20}$/MgO interfaces of dual-MgO free layers (FLs) in bottom-pinned magnetic tunnel junctions (MTJs). MTJ sta…
