Samarium is a gray-white metallic element of the lanthanide series, first identified spectroscopically in 1879. Its chief ores are monazite and bastnaesite. Samarium is used in carbon-arc lamps, as a moderator in nuclear reactors, and as a catalyst. Some samarium alloys are used for making powerful permanent magnets. Samarium's most common isotope is 152Sm (26.72%).
