Toyota develops heat-resistant magnet using less critical rare-earths

Toyota develops new magnet for electric motors aiming to reduce use of critical rare-earth element by up to 50%

The newly developed magnet uses no terbium (Tb) or dysprosium (Dy), which are rare earths that are also categorized as critical materials necessary for highly heat-resistant neodymium magnets. A portion of the neodymium has been replaced with lanthanum (La) and cerium (Ce), which are low-cost rare earths, reducing the amount of neodymium used in the magnet.
