Samarium (Sm) is a rare earth, silvery-white metal with atomic number 62, known for its strong magnetic properties, especially when alloyed with cobalt to create high-temperature permanent magnets. It's used in electronics, nuclear reactor control rods, and special glasses, with a radioactive isotope (samarium-153) also used in medical treatments for cancer. Discovered in the late 19th century, it occurs in minerals like monazite and bastnasite.
