Analytic Expression

We report a theoretical study on the bias dependence of the current-induced torque in the noncollinear ferromagnet/barrier/ferromagnet (FM) tunnel junction. By using the Keldysh–Green function technique, we derived an analytic expression of the spin transfer torque (STT) based on a continuum model. It was found that for finite bias, the torque induced by current increases monotonically with bias and is nearly antisymmetric with regard to the current direction, which agrees with the experimental observation on the STT in the spin valve system.
