Definition: | phenomenon in which a superconducting state appears within about one coherence length from the surface of a material, even under a magnetic field strength above the upper critical field strength
Note 1 to entry: If the magnetic field is parallel to the surface of the sample, surface superconductivity appears within a range of a magnetic field strength from to for type II superconductors, and from to for type I superconductors. Note 2 to entry: This entry was numbered 815-10-41 in IEC 60050-815:2015.
