Electrical signals transmitted via spin waves
Physicists in Japan have for the first time been able to transmit an electrical signal over a distance of one millimetre through an insulator using spin waves. The technique, which involves converting an electrical current into a spin signal and then back again, could be used in "spintronic" devices that exploit both the spin and charge of the electron. Such devices are of great interest because they could be smaller and more energy efficient than conventional electronic circuits.
