CMI researchers at Ames Laboratory conducted the activity for this highlight

Innovation
Novel cerium-based magnets for U.S. national needs

Achievement
Discovery of new 2:7-type Cerium-Zirconium-Cobalt-Iron composite ferromagnetic system with magnetic characteristics suitable for development of material cost effective permanent magnet material

Significance and Impact
Material develops significant extrinsic magnetic properties, e.g., coercivity and squareness of the hysteresis loop, readily after synthesis and allows utilization of abundant domestic Cerium (50% of Mountain Pass ore)

Hub Target Addressed 
Win industry adoption of three technologies related to materials substitution for rare earth magnet materials
