European researchers have devised a new way to make nanoparticles that could replace rare-earth material use in magnets. The researchers used a mixed iron-cobalt oleate complex in a one-step synthetic approach to produce magnetic core-shell nanoparticles. The resulting materials showed strong magnetic properties and energy-storing capabilities. The approach could signal an efficient new strategy toward replacing rare earths in permanent magnets such as those uses in electric motors and keeping costs stable, the researchers said. A paper on their work is published in the ACS journal Chemistry of Materials . … bi-magnetic core|shell (CS) nanoparticles (NPs) have attracted considerable interest over the last decades, due to the many intriguing phenomena stemming from the coupling […]
