The researchers will present their findings today at the American Chemical Society (ACS) Spring 2019 National Meeting & Exposition.
"We have developed new ways to better predict which materials make good magnets," says Thomas Lograsso, Ph.D., who led the team. "Experimentally, we can 'rehabilitate' near-magnet systems, called paramagnets. We start with alloys or compounds that have all the right properties to be ferromagnetic at room temperature. Many times, these materials have high proportions of iron or cobalt."
