El samario es un lantánido moderadamente duro empleado en imanes de samario-cobalto. Estos imanes resisten la desmagnetización a altas temperaturas.

Acerca de Samario

Samarium (Sm) is a moderately hard, silvery lanthanide, element 62, in period 6 of the f-block. Its atomic mass is 150.36, its electron configuration [Xe] 4f⁶ 6s², and its Pauling electronegativity 1.17. The element is central to samarium-cobalt permanent magnets, which are prized for retaining their magnetism at high temperatures where other magnets would fail, suiting them to aerospace and defense hardware. Samarium also finds use in certain catalysts and lasers. Solid at standard conditions, it commonly takes the +3 oxidation state, though the less usual +2 state is also accessible.
