Figure of a Spin Battery Device (IMAGE) University of Delaware Caption Scientists in the emerging field of spintronics are working to harness the spin or magnetic currents from electrons to encode and process data. This figures shows a spin battery device. A microwave induces magnetic resonance in a magnetic layer (blue), which will generate a "spin current," in which equal amounts of spin-up and spin-down electrons flow in opposing directions. The bottom magnetic layer (green) converts the spin current to a voltage for detection.
