30 MGOe energy product in 40% Nd-reduced MM-Nd-Fe-B magnet 

Hysteresis loops of the indicated magnets. Upon optimization of the RE ratio, the magnet achieved a coercivity of 7.3 kOe, and (BH)max of 30.3 MGOe. Inset: measured magnetizations, remanence and coercivity.

CMI researchers at Ames National Laboratory conducted the research for this highlight

Innovation
An NdFeB-based magnet with 40% of the Nd replaced by abundant rare earths La and Ce achieved an energy product of 30 MG-Oe.

Achievement
Performance approaching that of entry-level grades of NdFeB magnets at reduced cost and effective criticality.

Significance and Impact
Simultaneous usage of La and Ce may enable substantial effective criticality reduction. Usage of Mountain Pass mischmetal component convenient but innovation is performance at reduced Nd usage.

Hub Goal Addressed
Industrial adoption of CMI Technologies.
