CMI created a table of more than 450 recent U.S. patents that address rare earth magnet compositions and processes. Table updated Feb. 4, 2015.
Research to find substitutes for rare earth elements in permanent magnets includes running simulations on supercomputer Titan at Oak Ridge National Laboratory. Bruce Harmon at Ames Laboratory leads a project to create computational methods for exploring material structure and composition in non–rare earth permanent magnets. https://www.olcf.ornl.gov/2014/12/10/researchers-call-on-titan-to-help-solve-the-shaky-future-of-rare-earth-magnets/
