List of superconductors

From Wikipedia, the free encyclopedia

The table below shows some of the parameters of common superconductors. 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 tesla. "BCS" means whether or not the superconductivity is explained within the BCS theory.

Notes

  1. [1]
    According to,[4] superconductivity in Bi is not compatible with conventional BCS theory because the Fermi energy of Bi is comparable to the phonon energy (Debye frequency).
