Harnessing Diamagnetic Anisotropy for the Synthesis of Rare-Earth Free Magnets

With the decreasing supply of rare-earth metals and the increasing incorporation of strong magnets into renewable energy technologies, replacing rare-earth magnets has become a priority. Eliminating rareearth metals from magnets requires introducing a novel source of magnetic anisotropy. This seed project investigates the synthesis of new magnets that derive their anisotropy from diamagnetic sources, focusing on heavy main group elements such as bismuth. Although the approach of imparting anisotropy to paramagnetic metals from diamagnetic ions is well developed in the context of molecular magnets, thus far, it has not been applied to solid-state systems. The new magnets we synthesize will use earth abundant metals for cheaper renewable energy technologies, with applications in wind turbines and electric cars.
