Smartphones may one day look just as obsolete as flip phones thanks to spintronics, an incipient field of research that uses electrons’ spins to transfer electronic signals. Researchers now report a keystone achievement: the development of a conducting system that controls the spin of electrons and transmits a spin current over long distances, without the need for the ultra-cold temperatures required by typical conductors.
