A method for reducing spin-torque current density needed to switch a magnetoelectronic device (200, 300, 400), includes applying (602) a voltage bias having a predetermined polarity to the magnetoelectronic device (200, 300, 400) that creates a spin-polarized current with spin torque transfer to a synthetic antiferromagnet free layer (206), applying (604) a magnetic field having a predetermined direction to the magnetoelectronic device (200, 300, 400), removing (606) the applied magnetic field; and removing (608) the voltage bias subsequent to removing (606) the applied magnetic field, wherein the polarity of the voltage bias and the direction of the magnetic field leave the synthetic antiferromagnet free layer (206) in a predetermined magnetic state after the voltage bias is removed.
