Abstract

We show that the exchange splitting asymmetry between the left and right ferromagnetic leads in non-collinear magnetic tunnel junctions (MTJ) tunes the bias behavior of the field-like spin torque, T. These results can be understood by our recently derived general expression, which relates the non-collinear T to the algebraic sum of four independent non-equilibrium interlayer exchange couplings (IEC) solely in collinear configurations.
