Northeastern University researchers have designed a super-strong magnetic material that may revolutionize the production of magnets found in computers, mobile phones, electric cars and wind-powered generators.
The research was supported by a three-year, $360,000 grant from the National Science Foundation. The findings — which dovetail with Northeastern’s focus on use-inspired research that solves global challenges in health, security and sustainability — will be published in an upcoming edition of the journal Applied Physics Letters.
“State- of-the-art electric motors and generators contain highly coercive magnets that are based on rare-earth elements, but we have developed a new material with similar properties without those exotic elements,” said coauthor Don Heiman, a physics professor in the College of Science.
Heiman’s work aligns with Northeastern’s existing expertise in this area. The university’s Center for Microwave Magnetic Materials and Integrated Circuits, for example, works to develop next-generation microwave materials and device solutions for radar and wireless communication technologies for U.S. defense and commercial industries.
