Electronic Acrobats: Tidily tweaking electrons' twirls

6:43pm, February 19, 2003

Controlling a quantum trait of electrons that could be vital for future computers may just have gotten easier. Instead of manipulating electrons' spins with microscale magnetic fields, which tend to be weak and sluggish, researchers in California and Pennsylvania have devised a simpler, electric means of controlling the spins.

The scientists did their experiments at a temperature near absolute zero. However, if the new tactic can work at room temperature, it would remove a major obstacle to the development of so-called spintronics–circuitry that exploits electronic spin in addition to electronic charge, says David D. Awschalom of the University of California, Santa Barbara.
