From: Strain-enhanced tunneling magnetoresistance in MgO magnetic tunnel junctions
Non-equilibrium Green's function simulations.
(a) Fe/6-layer MgO/Fe model used in the quantum transport simulations. The Fe(100) contacts are semi-infinite. (b) Percentage change in the parallel (1.7 × 10−5 e2/h) and antiparallel (9.1 × 10−8 e2/h) conductance and optimistic TMR ratio as a function of biaxial xy-strain. (c) k//-resolved transmission coefficients, T(EF), for majority states, parallel configuration and (d) antiparallel configuration for the unstrained junction.
