CMI researchers from Ames National Laboratory conducted the activity for this highlight
Innovation
Novel cerium-based magnets for U.S. national needs.
Achievement
Development of RM-stabilized (Ce,Nd)Fe12 phases (RM = Zr, Mo) and their nitrides with magnetic characteristics suitable for development of cost-effective high-energy magnets.
Significance and impact
- New magnet materials containing low amounts of critical elements (< 10 wt. % Nd) and employing abundant domestic Cerium (50 % of MP ore).
- Upon nitrogenation Curie temperature (TC) increases from 424 to 661 K and reaches as high as 673 K for 9.7 weight percent Nd.
- High temperature stability, with decomposition temperatures (TD) beyond 930 K.
Hub Target Addressed
Accelerated magnet discovery and maturation
