NOVAMAG–Novel, Critical Materials Free, High Anisotropy Phases for Permanent Magnets, by Design.
The demand for lower dependency on critical raw materials (CRM) such as rare earths (RE) is not only a European but a global problem that demands immediate action. The purpose of this project is to exploit advanced theoretical and computation methods together with state-of-the-art materials preparation and characterization techniques, to develop the next generation RE-free/lean permanent magnets (PM). The material design will be driven by automated large computational screening of new and novel intermetallic compounds with uniaxial structure in order to achieve high saturation magnetisation, magnetocrystalline anisotropy and Curie temperature. The simulations will be based on a primary screening detecting the mechanisms that give rise to distorted phases and stabilize them, by adding doping atoms as stabilizers. In a further computation on successfully synthetized compounds, micromagnetic calculations will be used in order to design the optimal microstructure for the given phases that will maximise the coercivity needed for a PM. Extensive experimental processing and characterisation of the selected phases will result in a first proof of principle of the feasibility of NOVAMAG PMs. A multidisciplinary team of magnet experts consisting of chemists, material scientists, physicists and engineers from academia, national labs and industry is assembled to undertake a concerted, systematic and innovative study to overcome the problems involved and develop the next generation RE-free/lean PMs. Currently the demand for these PM s is even higher with the emerging markets of hybrid/electric vehicles and wind mill power systems. The proposed project will provide the fundamental innovations and breakthroughs which will have a major impact in re-establishing the Europe as a leader in the science, technology and commercialization of this very important class of materials and help decrease our dependence on China, which will in turn improve the competitiveness of EU manufacturers.
