We present a calculation of current-induced torques in metallic magnetic multilayers derived from the spin-dependent transmission and reflection properties of the magnetic layers. A scattering formalism is employed to calculate the torques in a magnetic-nonmagnetic-magnetic trilayer, for currents perpendicular to the layers, in both the ballistic and diffusive regimes.

• Electric field control of spin transport (2005, background): “In addition, the energy levels E n of the carbon-nanotube quantum dot acquire a spin-dependent part caused by phases of the reflection amplitudes at the boundaries between the quantum dot and the ferromagnetic electrodes, which are spin dependen”
