Scientists looking for alternatives to RE have reported in ACS’ journal Chemistry of Materials (“Strongly exchange coupled core|shell nanoparticles with high magnetic anisotropy: a strategy towards Rare Earth -free permanent magnets”) a new way to make nanoparticles that could replace some rare-earth materials and help ensure the continued supply of products people have come to depend on.
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.
