Title: Manganese-Aluminum-Based Magnets: Nanocrystalline t-MnAI Permanent Magnets

REACT Project: Dartmouth is developing specialized alloys with magnetic properties superior to the rare earths used in today’s best magnets. EVs and renewable power generators typically use rare earths to turn the axles in their electric motors due to the magnetic strength of these minerals. However, rare earths are difficult and expensive to refine. Dartmouth will swap rare earths for a manganese-aluminum alloy that could demonstrate better performance and cost significantly less. The ultimate goal of this project is to develop an easily scalable process that enables the widespread use of low-cost and abundant materials for the magnets used in EVs and renewable power generators.
