A new type of metallic state of matter has been discovered by an international team of researchers studying a superconductor made from carbon-60 molecules or “buckyballs”. The team found the new state after changing the distance between neighbouring buckyballs by doping the material with rubidium. The study reveals that the material has a rich combination of insulating, magnetic, metallic and superconducting phases – including the hitherto unknown state, which the researchers have dub a “Jahn–Teller metal”……
