Overview:
We are seeking to either drastically reduce the heavy rare-earths (HRE) in high-temperature permanent magnets (e.g. Nd-Fe-B) or to totally replace rare-earth magnets by other means, while maintaining comparable or improved coercivity and magnetization.
Background:
Permanent magnets are particularly crucial within the rapidly-developing e-mobility sector, where the motors for electric vehicles require strong magnets with the ability to operate at temperatures above 150°C. To achieve high temperature stability, rare earth elements are often used. It would be advantageous to find replacements.
Constraints:
- High temperature stability above 150C
- Low cost material approach
- Good magnetic characteristics, comparable to Neodymium (Nd-Fe-B)
Possible solution areas:
- Materials science
- Motor and magnet research
Desired outcome of the solution:
Proposal of material that can act as a direct replacement for rare earth materials in electric motors.
Field of use and intended applications:
Vehicle industry.
