The Incredible Pull of Nanocomposite Magnets: Nanotechnology could make rare earth magnets even stronger

Abstract:
In the past, when researchers went looking for ways to make better permanent magnets, they were pretty much restricted to combining various mostly metallic elements into a single magnetic alloy. Now some of us are pushing an entirely different approach: We hope to construct ultrastrong magnets using two different alloys combined at the nanometer scale. That's not an easy thing to do, but if researchers can overcome the remaining technical obstacles, such "nanocomposite magnets" could allay worries over the dwindling supply of neodymium. And such magnets could make motors, generators, loudspeakers, and the like more compact and efficient, which is a worthwhile goal in itself.
