Rare Earth Elements: Their Importance in Understanding ...

The rare earth elements (REEs) are commonly defined as lanthanum (La) and the 14 elements comprising the Lanthanide series. The REE’s typically exhibit trivalent oxidation states; however, Europium may also occur as Eu 2+ and Cerium may occur as Ce 4+ . The REE’s ionic radii decrease on progression from La to Lu, which results in a slight but predictable change in their chemical affinity.

The rare-earth metals have high magnetic moments and a diverse range of magnetic structures. Their magnetic properties are determined by the occupancy of the strongly localized 4f electronic shells, while the outer s-d electrons determine the bonding and other electronic properties. Most of the rare-earth atoms are divalent, but generally become trivalent in the metallic state.
