New property in warm superconductors discovered: "Sonier and his colleagues used a subatomic particle, called a muon, to microscopically probe the magnetic nature of a cuprate. This led them to discover that a strange kind of magnetism appears to accompany the destruction of superconductivity during high chemical doping.
The scientists are now trying to figure out the origin of the magnetism and whether it actually competes with superconductivity.
Sonier says, “Understanding what destroys superconductivity during high chemical doping could provide a vital clue about the microscopic mechanism responsible for high-temperature superconductivity. Knowledge of this would be a monumental step toward making a room-temperature superconductor.”"
