{wiki=Samarium_hexaboride}
Samarium hexaboride (SmB6) is a compound composed of samarium, a rare-earth element, and boron. It crystallizes in a complex cubic structure and is noted for its notable electronic properties. SmB6 is particularly interesting to researchers because it exhibits behavior characteristic of a topological insulator. In its bulk form, SmB6 is an insulator at low temperatures, but it has metallic-like surface states that can conduct electricity.
