The rare earth elements (REEs) or rare earth metals (REMs) are a group of metals found within the same ores and possessing similar chemical properties. Scientists and engineers disagree on exactly which element should be included in a list of the rare earths, but they generally include the fifteen lanthanide elements, plus scandium and yttrium.
American Chemical Society: Chemistry for Life. ... But rare-earth elements can be difficult to obtain, given either their scarcity or the challenging geopolitical climates of some of the nations where they are mined. Now, scientists have identified magnets based on more readily obtainable rare earths, as well as some promising magnets that don ...
