Samarium sputtering target is a silver target made of high-purity samarium (Sm) metal. It has a melting point of 1072°C, a boiling point of 1791°C, and a density of 7.52 g/cm3. It is relatively stable in dry air, but will oxidize in contact with moisture. Samarium is a rare earth metal having a hardness and density similar to those of zinc.
One of the most important applications of samarium is in samarium–cobalt magnets, which have a nominal composition of SmCo5 or Sm2Co17. They have high permanent magnetization, which is about 10,000 times that of iron and is second only to that of neodymium magnets. However, samarium-based magnets have higher resistance to demagnetization, as they are stable to temperatures above 700 °C (cf. 300–400 °C for neodymium magnets).
