Abstract:
The transition toward a sustainable energy future requires materials that are not only efficient but also environmentally responsible and resource conscious. Magnetic materials stand at the heart of this transformation, enabling technologies that range from power generation and refrigeration to sensing and actuation. Recent advances in sustainable magnetism are reshaping the field, with innovations that reduce reliance on scarce rare-earth elements, introduce recyclable pathways, and exploit additive manufacturing to create complex, high-performance architectures.
First, we will discuss breakthroughs in the design of rare-earth-lean and rare-earth-free permanent magnets, as well as emerging strategies for the recycling and upcycling of NdFeB-based waste magnets, aiming to alleviate supply-chain risks and reduce dependence on critical raw materials. We will then turn to magnetocaloric materials, focusing on novel processing routes for functional magnetocaloric inks and their validation through additive manufacturing of efficient heat exchangers using direct ink writing 3D printing techniques, a step toward scalable, eco-friendly magnetic refrigeration. Finally, we will present preliminary results on Pd-based alloys as highly sensitive hydrogen sensors, showcasing their capability for both direct-contact and wireless detection.
Together, these advances illustrate how magnetic materials can provide sustainable solutions for energy, refrigeration, and hydrogen technologies, paving the way toward a cleaner and more resilient technological landscape.
