Physicists control the flip of electron spin

Today's computers and other technological gizmos operate on electronic charges, but researchers predict that a new generation of smaller, faster, more efficient devices could be developed based on another scientific concept – electronic "spin." The problem, however, is that researchers have found it challenging to control or predict spin – which keeps practical applications out of reach.
But physicists in Europe, California and at Ohio University now have found a way to manipulate the spin of an electron with a jolt of voltage from a battery, according to research findings published in the recent issue of the journal Physical Review Letters.
