Researchers from IBM and European university ETH Zurich have announced they have directly mapped the formation of a persistent spin helix in a semiconductor for the first time. They observed how electron spins move in a semiconductor while rotating, like couples doing a waltz. This will let them manipulate the spin, which is a crucial step toward developing spin-based transistors that can be electrically programmed. That, in turn, could help achieve more efficient means of storing data.
