Caption: A new "spintronic" organic light-emitting diode glows orangish (center) when the device, chilled well below freezing, is exposed to a magnetic field from the two poles of an electromagnet located on either side of the device. University of Utah physicists report inventing the new kind of LED in the July 13 issue of the journal Science.
