REEs-free high-performance permanent magnets based on exchange-spring and high anisotropy phases
Permanent magnets (PMs) have critical applications in wind power generation, widely employed in Portugal. The performance of PM materials relies heavily on the presence of rare-earth elements (REEs), however, their status as critical raw materials (CRMs) calls for new approaches in developing alternative PMs that present minimal content/ absence of CRMs. The targeted breakthrough of the CritMag is to establish a new synthesis methodology for the fabrication of REE-free high-performance PMs. This objective is mainly achieved through the engineering of nanostructures with strong magnetic and shape anisotropy. The fabrication is based on our know-how in large-scale synthesis of colloidal magnetic nanoparticles with excellent magnetic properties. The method is well suited for the implementation of up-scalable and cost-efficient fabrication of REE-free PMs. Our targeted application is an electric energy generation device and we will manufacture a prototype generator using the CritMag PMs.
