Ames Lab scientists develop AI-driven method to create magnets without rare earth metals

Scientists at the Ames National Laboratory in the U.S. have developed a systematic path to the discovery of new approaches to building permanent magnets without relying on rare-earth elements.

The approach combines physics-based modeling and high-throughput simulations with reasoning-based artificial intelligence (AI) tools to guide the discovery process even before materials are made in the laboratory.

Permanent magnets are a crucial part of our everyday lives. From aiding data storage to helping us drive electric vehicles (EVs) to enabling high-quality medical imaging, permanent magnets
