Spintronics: Could diamonds be a computer's best friend?

For the first time, physicists have demonstrated that information can flow through a diamond wire. In the experiment, electrons did not flow through diamond as they do in traditional electronics; rather, they stayed in place and passed along a magnetic effect called "spin" to each other down the wire -- like a row of sports spectators doing "the wave." Spin could one day be used to transmit data in computer circuits -- and this new experiment revealed that diamond transmits spin better than most metals in which researchers have previously observed the effect.
