Nanostructured High-Strength Permanent Magnets
University researchers are developing nanocomposite high-strength permanent magnets and methods to fabricate said magnets. The invention provides various configurations of hard magnet and soft magnet nano regions that enhance the exchange-coupling between these regions, thus leading to greater magnetic strength. In this way next-generation permanent magnets can be produced in bulk at lower cost and reduced risk compared to current permanent magnets that depend on scarce and globally critical rare-earth minerals. Such new nanostructured high-strength permanent magnets can find applications in the growing hybrid/electric vehicle and wind turbine generator industries.
