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.
Nanoparticles of gadolinium oxide is a potential contrast agent for magnetic resonance imaging (MRI). A dextran-coated preparation of 20–40 nm sized gadolinium oxide particles had a relaxivity of 4.8 s −1 mM −1 per gadolinium ion at 7.05 T (an unusually high field compared to the clinically used MRI scanners which mostly range from 0.5 to ...
Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.

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.
The mineral species Xenotime-(Gd) was approved by the IMA in 2023, [3] a description of the mineral was published in 2024 based on crystals found within gadolinium rich xenotime-(Y) sampled at the Zimná Voda quartz vein near Prakovce. [4] Besides yttrium, the examined type material bore further rare earth elements such as dysprosium, samarium ...
