The threshold temperatures of these materials are related to the critical strength of their external magnetic fields by Tuyn's law. The London moment is the magnetic field created when one of these is spinning. When certain materials transition to this type of material, they expel their magnetic field in an effect named after Meissner. In BCS theory, these are formed when electrons condense into Cooper pairs. Coming in Type I and Type II varieties, for 10 points, name this type of material that has zero electrical resistance.
