Theoretical modelling of alloys for rare-earth-free high-performance permanent magnets

Research question

First, we will understand unexpectedly high cooling rates that have been achieved experimentally upon casting of L10 FeNi doped with P. In the second stage of the project, we will investigate the possibility of synthesis of L10 FeNi via layer-by-layer thin film growth followed by annealing at temperature below the ordering temperature Tord. Finally, we will explore the concept of alloying with multiple principal elements to further improve magnetic properties of FeNi-based alloys.

Sustainability aspects

Development of the non-rare-earth permanent magnets belongs to the research frontier within modern materials science, addressing several UN Sustainable Development Goals. Successful development of FeNi-based permanent magnets will secure the supply of high-performance magnets and reduce the environmental impact associated with the extraction of the rare-earth elements. It will enable engineers to harvest energy from wind, improve electric vehicles and construct and operate infrastructure from sustainable functional materials.
