Nanomagnets tapped to generate microwave fields

Abstract:
A new form of electromagnetic interaction in which electron spin changes the magnetic direction of cobalt nanomagnets is being explored at Cornell University with an eye toward new types of memory and signal-processing devices. Experiments have shown that the impact of spin-polarized electrons causes the nanomagnets to precess at high speed so that a direct current can produce microwave-frequency oscillations.
