| Abstract Scope |
Magnetic materials are crucial for the global energy transition, particularly in green technologies. High-performance hard magnets are key components in applications like direct drive wind turbines and electric mobility. Both soft and hard magnets are also vital in robotics, sensors, actuators, and information technology. Rare earth elements (REEs) are essential for high-performance magnets and achieving a net-zero emission future in the EU. However, the REEs supply chain faces several challenges, and shortages could hinder climate change technologies and other key sectors. To secure a sustainable supply chain, we need to diversify raw materials, design better alloys, find substitute materials, and improve recycling methods. This discussion will cover material requirements, performance metrics, demand and supply, and the criticality of strategic elements using SmFe12-based compounds as an example. Additionally, recycling processes and efficient utilization of heavy rare earths in Nd-Fe-B magnets, along with new research in compositionally complex alloys will be explored. |
