Rare-earth magnets are essential for electric motors in vehicles, drones, and trains, forming the backbone of modern, ...

Researchers from the Department of Energy’s Critical Materials Institute (CMI) and Ames National Laboratory have improved the properties of a rare-earth-free permanent magnet material and demonstrated ...

A new tomography-based approach can reconstruct the real microstructure of ultrafine-grained Nd-Fe-B magnets in large-scale models. Micromagnetic simulations on the tomography-based models reproduced ...

Researchers at the Korea Institute of Materials Science (KIMS) have developed rare-earth-saving permanent magnets that can replace the 42M-graded commercial magnets while reducing the amount of ...

The left side of the figure schematically shows how a series of two-dimensional scanning electron microscopy images of an ultrafine-grained Nd-Fe-B magnet were transformed into a three-dimensional ...
