Phys.org  October 18, 2022 Researchers have been searching for new magnetic materials that can act as substitutes for the critically scarce components. Researchers at Northeastern University have patented a process to accelerate the creation of a rare earth magnet alternative using tetrataenite, whose magnetic properties make it a leading candidate to replace magnets made of the scarce material. To make the new magnet they altered the atomic structures of its iron and nickel components by arranging them into a crystal structure that resembles tetrataenite. Industrial permanent magnets are used to transfer energy from mechanical to electrical sources. The list of […]
