From: Highly Enhanced TMR Ratio and Δ for Double MgO-based p-MTJ Spin-Valves with Top Co2Fe6B2 Free Layer by Nanoscale-thick Iron Diffusion-barrier

Figure 7

Two types of atomic structure. Atomic structures of (a) the interface between the W capping layer and the MgO capping layer and (b) the interface between the W capping layer, nanoscale Fe diffusion barrier, and MgO capping layer of double MgO-based p-MTJ spin-valves with top Co2Fe6B2 free layer. Here, (–) corresponds to compressive strain while ( + ) corresponds to tensile strain.
