What they work on
- Synthesize new cerium compounds containing transition metals and heavy chalcogen elements such as selenium or tellurium, using crystal growth and solid-state reactions, to search for unusual electronic states.
- Improve the magnetic performance of cerium–iron permanent magnet materials by controlling their composition and processing, including thin-film deposition and plasma-assisted treatments.
- Characterize the crystal structure, magnetic properties and electronic properties of the new materials to link structure and composition to magnetic behavior and guide the design of better magnets.
More about the research
Cerium is the most abundant rare earth element, so it could stand in for scarcer ones. This project asks how cerium-containing materials can be made into stronger magnets. It also looks for new magnetic compounds with unusual electronic behavior.
Why it matters
Permanent magnets in electric motors and electronics depend on scarce rare earth elements. Learning how to make strong magnets from cerium, the most abundant rare earth, could reduce reliance on these scarce elements. It could also lead to more efficient magnetic materials for motors and new electronic devices. New cerium compounds with unusual electronic states may also point toward future electronic technologies.
