CMI researchers from Ames National Laboratory conducted the activity for this highlight
Innovation
Novel cerium-iron-based magnets for U.S. national needs.
Achievement
- Development of new critical-element-free Fe-rich alloy with intrinsic magnetic properties sufficient for development of high-energy permanent magnet, i.e., Ha > 8 T, Ms > 12 kG, Tc > 500 K.
- Small Sm doping (< 10 wt.%) of W-stabilized CeFe12 bulk alloys facilitates strong uniaxial magnetocrystalline anisotropy.
Significance and Impact
Novel critical-element-free permanent magnet material that consists of ~75 wt.% Fe and uses domestic earth-abundant, inexpensive Ce.
Hub Target Addressed
Accelerated magnet discovery and maturation.
