Abstract

Nanomagnets in a spin Magnetic thin film multilayers have many applications for data storage, semiconductor memories and as sensors. The spin-torque effect, which uses an electric current to rapidly spin the material's magnetic constituents, could lead to new applications for this technology at ever-smaller scales: think in terms of a radio set the size of a bacterium. Two groups have now independently achieved synchronization — or phase-locking — of the magnetic oscillations of two such nanomagnets placed just 400–500 nm apart. These oscillations can generate microwave signals for telecommunication and an array of these nanomagnets could also act as a receiver, enabling microchips to communicate without being in physical contact, greatly enhancing computing speed.
