Samarium est principalement utilisé dans la production de samarium-cobalt (Sm2Co17) des aimants permanents. Il est également utilisé dans les applications laser et pour ses propriétés diélectriques.

Samarium is a chemical element with symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air. Being a typical member of the lanthanide series, samarium usually assumes the oxidation state +3. Compounds of samarium(II) are also known, most notably the monoxide SmO, monochalcogenides SmS, SmSe and SmTe, as well as samarium(II) iodide.
