Attractive news for nanotech magnets

Rare earth elements like neodymium, dysprosium, and turbium may not be household words, but they are critical ingredients in the strong magnets that are vital to everything from wind turbines to auto engines. But with the future supply of such elements in question due to political and economic factors, it appears nanotechnology could be coming to the rescue. According to Popsci.com, researchers have devised a way to use nanocomposite materials to boost the magnetism in alloys, meaning less rare earth materials need to be used. Since these magnets are also smaller and lighter to boot, this sounds like, dare we say, positively attractive news for the future of high-tech magnets.
