CMI at Ames National Laboratory conducted the activity for this highlight
Innovation
Ce-Fe-based magnets for U.S. national needs.
Achievement
- Development of the new critical-element-free Fe-rich alloy with intrinsic magnetic properties sufficient for development of high-energy permanent magnet, i.e., Ha > 4.5 T, Ms > 13.5 kG.
- Small Sm doping (< 10 wt.%) of Zr/Mo-stabilized CeFe12 bulk alloys facilitates large magnetocrystalline anisotropy sufficient for strong permanent magnets.
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.
