Permanent magnets are crucial in modern technology as they allow storing, delivering and converting energy. They are able to transform electrical energy into mechanical and vice versa, which means that improving their performance entails transforming energy in a more efficient and sustainable way.

The best magnets are based on rare-earths (RE), however, their status as a Critical Raw Material (CRM) has brought forward the realization that it is of great strategic, geographic and socio-economic importance to consider alternative magnets that present a reduced amount (or absence) of RE. One of the most sought approaches towards this goal consists on constructing composite magnetic materials magnetically coupled at the interface.

The goal of AMPHIBIAN is to implement up-scalable and cost-efficient methods for fabrication of ferrite-based  magnets with a 40% enhanced magnetic performance with respect to commercial ferrites. We aim at producing improved magnets that retain the advantages of ferrites –availability, sustainability, cost, recyclability- and which have the potential to substitute currently used RE magnets (CRM) in the electric power system.

Our targeted application is an electric energy storage device: we will substitute RE magnets by AMPHIBIAN ones in a demonstrator of a flywheel and evaluate its performance against cost, eco-friendliness and resource efficiency criteria.

AMPHIBIAN is coordinated by Dr. Adrian Quesada, researcher at the Instituto de Cerámica y Vidrio (CSIC) and Secretary of the Basic Science Section of the Spanish Society of Ceramics and Glass (SECV).
