  • RARE-EARTH-FREE OR NOBLE METAL-FREE LARGE MAGNETIC COERCIVITY NANOSTRUCTURED FILMS
    Publication number: 20130236720
    Abstract: Rare-earth-free, noble-metal-free nanostructured magnetic material thin films and methods of synthesis are described. Magnetocrystalline, ferrimagnetic thin films with islands of aligned single magnetic domains possess large coercivity. In particular, MnxGa thin films are described. These materials provide a potential substitute to rare-earth-based and noble-metal-based magnets in applications related to electric motors and generators, audio headphones and speakers, recording media and magnetic hard drive memory.
