CMI Project 2.3.4 Tailored synthesis in nanoparticle permanent magnets (NPPM)

This project will leverage expertise in materials synthesis, characterization and modeling to realize nanoparticle permanent magnets (NPPM) primarily composed of earth abundant elements (iron and nitrogen). The project will address the challenges in forming dense, grain aligned magnets without decomposing the magnetic phase or degrading magnetic properties. Processing informed by atomistic modeling will guide the formation, growth, and stability of the NPPM and their grain boundary phases. Methods for maintaining coercivity during compaction to reach 90% alignment by volume and 95% densification will be guided by advanced characterization to inform models and validate novel processing routes.
