Nanoscale oscillaters work together for stronger signal

Groups of nanoscale magnetic oscillators are known to synchronize their individual 10-nanowatt signals to achieve a signal strength equal to the square of the number of devices. Now scientists at the National Institute of Standards and Technology (NIST), Seagate Research Center (Pittsburgh, Pa.) and Hitachi Global Storage Technologies (San Jose, Calif.) have discovered how—the oscillators accomplish this feat by communicating by means of “spin waves,” their magnetic emissions caused by oscillating patterns in the spin of electrons. Thanks to nanotech-now.com for the heads up on this artile.
