Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with an attraction to a magnetic field higher than that of nickel.
All of the world's heavy rare earths (such as dysprosium) come from Chinese rare-earth sources such as the polymetallic Bayan Obo deposit. [ 44 ] [ 46 ] The Browns Range mine, located 160 km south east of Halls Creek in northern Western Australia , was under development in 2018 and is positioned to become the first significant dysprosium ...

Any rare-earth element can be used in a ReBCO; popular choices include yttrium (), lanthanum (), samarium (Sm123), [6] neodymium (Nd123 and Nd422), [7] gadolinium (Gd123) and europium (Eu123), [8] where the numbers among parenthesis indicate the molar ratio among rare-earth, barium and copper.
Gadolinite, sometimes known as ytterbite, is a silicate mineral consisting principally of the silicates of cerium, lanthanum, neodymium, yttrium, beryllium, and iron with the formula (Ce,La,Nd,Y) 2 FeBe 2 Si 2 O 10.

The element gadolinium and its oxide gadolinia were named after Gadolin by its discoverers. [ 21 ] In an earlier paper in 1788 Gadolin showed that the same element can show several oxidation states, in his case Sn(II) and Sn(IV) 'by combining itself with larger or smaller amounts of the calcinating substance'.
