Through a mechanism known as the Spin Hall effect, it has been shown that a voltage can be generated by harnessing differences in spin populations on a metal contact attached to a ferromagnetic material. Researchers used supercomputers to identify various forms of cobalt oxide combined with nickel and zinc that show promise for thermoelectric generation by taking advance of the Spin Hall effect.
