Article Summaries:
- Scientists at the University of New Hampshire have used artificial intelligence to accelerate the discovery of new magnetic materials that could replace rare‑earth magnets in electric vehicles and other technologies. The team built the Northeast Materials Database, cataloguing 67,573 magnetic compounds, including 25 previously unknown materials that remain magnetic at high temperatures. By training models on data extracted from scientific papers, the AI predicts magnetic behavior and Curie temperatures, offering a cost‑effective, sustainable alternative to rare‑earth‑based magnets. The study, published in Nature Communications, highlights the potential to reduce dependence on imported rare earths and lower electric‑vehicle production costs.
