Samarium is a moderately hard silvery metallic element, belongs to the lanthanoids. Totally samarium has 38 isotopes. 7 of them are natural ones, 5 of which are stable. Sm-147 is the natural radioisotope, and it has a half-life of 1.06*10^11 years. Samarium is used for making special alloys needed in the production of nuclear reactors. This element is used as a neutron absorber too. Small quantities of samarium oxide is used in special optical glasses. The largest use of the element is its ferromagnetic alloy which produces permanent magnets that are five times stronger than magnets produced by any other material. Samarium was discovered by Francois Lecoq de Boisbaudran in 1879.
Samarium is used in the electronics and ceramics industries. Samarium is easily magnetized and very difficult to demagnetize. This suggests its important future applications in solid-state and superconductor technologies.
