Nanocrystalline Permanent Magnets Based on Hybrid Metal-Ferrites

Objective

This project addresses the design and development of permanent magnets without rare earths but consisting on hybrid nanostructures based on metals and metal ferrite oxides. The metallic nanostructures offers high magnetization values while the ferrite oxide one provides high anisotropy. We intend to design and process novel permanent magnets based on traditional hard ferrites and additional new magnetic phases combined with a soft magnetic phase to achieve high magnetic performance through effective exchange-coupling of both magnetic phases. This phenomenon has been extensively studied in metallic systems but not in oxide nanocomposite permanent magnets, where the studies are very scarce mainly due to the difficulty in optimizing the magnetic properties because of microstructural complexities. In view of practical applications this will guarantee their use in some nowadays applications which are currently covered by more expensive rare-earth permanent magnets, simply because typical ferrites do not fulfill the required magnetic energy product. This “no-man's-land” applications area - characterized by required energy products between 35 to 100 kJ/m3 - includes fundamental fields such as diverse components for transport and energy applications. As an important consequence, the use of rare-earth based permanent magnets will be reduced to its maximum possible extent by fulfilling the needs for a broad applications range by these newly designed rare-earth free permanent magnets.
This project is therefore important from a fundamental as well as from a practical point of view where the complementary expertise areas of the different groups will combine to achieve the proposed objectives.
