WebVery accurate measurement of small magnetic fields has only been practical since the discovery in 1988 of giant magnetoresistance in specially layered materials. This … WebPlasmons couple light to magnetic fields. The researchers are making minute “antennas”, tiny nanoscale rods, discs and balls, only billionths of a meter across. The antennas are attached to a transparent surface such as glass. When light strikes the antennas, it causes the electrons in them to oscillate. And unlike magnetic fields ...
