Rare earth (RE) metals have many unique properties, such as photic, electric, magnetic, and hydrogen storage properties, due to the unique unpaired 4f and 5f electrons structure and their rich energy levels structrue, which have been extensively investigated for their potential applications in various fields [1,2,3].Electrodeposition is a …

Laterite clays are a commercial source of the heavy lanthanides and yttrium. Other minerals that have been used as a source of rare earths are apatite, euxenite, gadolinite, and xenotime. Allanite, fluorite, perovskite, sphene, and zircon have the potential to be future sources of rare earths. (In addition, uranium and iron tailings have been ...

Rare earth elements are a group of seventeen chemical elements that occur together in the periodic table (see image). The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium).

Additionally, rare-earth oxides are regarded as potential candidates for high-k gate dielectrics because of their ability to form direct contact with silicon substrate [3]. Superconductors based on rare-earth oxypnictides [4], [5], [6] were also discovered with critical temperatures as high as 55 K [7] .
