Two new high-performance magnet technologies licensed by ORNL

CMI researchers from Oak Ridge National Laboratory conducted the activity for this highlight

Innovation 
Two new high-performance permanent magnet compositions developed by CMI have been licensed by United Rare Earths.

Achievement 
The licensed compositions were developed from CMI-funded theoretical efforts followed by experimental confirmation, as well as magnet synthesis work.

Significance and Impact 
The compositions – La- substituted Nd₂Fe₁₄B and Zr- and Fe- substituted Ce₂Co₁₇ – offer the promise of NdFe₁₄B-competitive performance at significantly reduced criticality and cost.

Hub Target Addressed 
Accelerated magnet discovery and maturation.
