Gadolinium , Gd
Gadolinium is a chemical element that has the symbol Gd and atomic number 64.
Gadolinium is a silvery-white, malleable and ductile rare-earth metal with a metallic lustre. It crystallizes in hexagonal, close-packed alpha form at room temperature, but, when heated to 1508 K or more, it transforms into its beta form, which has a body-centred cubic structure.

Gadolinium
Unlike other rare earth elements, gadolinium is relatively stable in dry air. However, it tarnishes quickly in moist air and forms a loosely-adhering oxide that spalls off, and then exposes more surface to oxidation. Gadolinium reacts slowly with water, and it is soluble in dilute acids.
Gadolinium-157 has the highest thermal neutron capture cross-section of any known nuclide with the exception of Xenon-135, 49,000 barns, but it also has a fast burn-out rate, limiting its usefulness as a nuclear control rod material.
Gadolinium becomes superconductive below a critical temperature of 1.083 K. It is strongly paramagnetic at room temperature, and exhibits ferromagnetic properties below room temperature.
Gadolinium demonstrates a magnetocaloric effect whereby its temperature increases when it enters a magnetic field and decreases when it leaves the magnetic field. The effect is considerably stronger for the gadolinium alloy Gd<sub>5</sub>(Si<sub>2</sub>Ge<sub>2</sub>).
