Superdiamagnetism

Superdiamagnetism (or Perfect diamagnetism) is a phenomenon occurring in certain materials at low temperatures, characterised by the complete absence of magnetic susceptibility and the exclusion of the interior magnetic field. Superdiamagnetism is a feature of superconductivity. It was identified in 1933, by Walter Meissner and Robert Ochsenfeld (the Meissner effect).

Superdiamagnetism established that the superconductivity was a stage of phase transition. Superconducting magnetic levitation is due to the Superdiamagnetism (which repels a permanent magnet) and flux pinning, which stops the magnet from sliding away.
