Durga Paudyal at Ames Laboratory leads the CMI project "Predicting magnetic anisotropy"

This project identifies, develops and employs novel methods to exploit f-elements for use in various novel rare earth lean magnet materials and d-elements for use in improved rare earth free permanent magnet materials by applying advanced theoretical and computational techniques. The research with rare earth lean materials aims at improving permanent magnet performance beyond the current champion neo-magnets while research with rare earth free materials aims at improving permanent magnet performance at the gap magnet level. The overarching objective is to provide theoretical support and guidance to various experimental magnet thrust projects to discover and develop high performance magnets.
