Scarlet X writes "Researchers at the University of Washington have discovered a possible nonvolatile magnetic semiconductor and are investigating its use for 'spintronics,' an emerging technology that is concerned with manipulating and controlling the charge, flow and magnetism of electrons. The possibilities for the material 'cobalt green,' a paint developed by American Revolution era artists, as a spintronics material is exciting. Should the magnetic properties of the paint at room-temperature prove able to reliably control the wild spinning of excited electrons in a processor, not only could the size of processors reduce substantially, but the constant limiting factor, how to keep things cool, could disappear."
