Abstract: In this paper, we model the effects of the physical properties of the capping layer, such as spin diffusion length (lsf cap), resistivity (ρcap), and interfacial conductance (G↑cap, G↓cap) on the spin transport across a pseudo-spin-valve (PSV) structure. In particular, we investigate how the properties of the capping layer can be modified in order to enhance the perpendicular component (τ⊥) of the spin transfer torque vis-a-vis the inplane (τ¶) component. The results suggest that the capping layer can serve as an effective medium for tuning the ratio of τ⊥ to τ¶ by varying its physical properties. © 2006 IEEE.
