List of superconductors

A table showing major parameters of major superconductors of simple structure (numerous metallic alloys are not shown). X:Y means material X doped with element Y, TC is the highest reported transition temperature in kelvins and HC is a critical magnetic field in teslas. "Non-metals" here refers to materials which are normally not considered as metals, but become superconducting upon heavy doping. "BCS" means whether or not the superconductivity is explained within the BCS theory.
