By Luqiao Liu, Robert J. Shillman (1974) Career Development Assistant Professor in the Department of Electrical Engineering and Computer Science: "We believe that spintronic devices with ultralow power consumptions could be finally achievable."
Figure 1: (a) Schematic illustration of the spin transfer torque mechanism in a ferromagnet/nonmagnetic spacer/ferromagnet tri-layer structure. The open circles with arrows represent the spin orientation of conduction electrons while the bold arrows illustrate the magnetic moment orientation of the two ferromagnet layer. (b) Illustration of the spin generation from spin Hall effect. Arrows with different colors represent the spin orientations at different surfaces.
