Abstract: 
We present a generalization of the coupled spin-charge drift-diffusion formalism capable of accurately describing the spin and charge transport properties through magnetic tunnel junctions. Correction terms enable reproducing oscillations of the spin current in ferromagnets typical for quasi-ballistic transport. Our approach proves necessary to accurately capture an interplay between the interfacial Slonczewski and bulk-like Zhang-Li contributions to the torque in ultra-scaled MRAM devices.
