The distance at which a magnetic field exponentially decays by a factor of one over e in one of these materials is known as the London penetration depth. They exist in Type I and Type II varieties, and they are mathematically described using Ginzburg-Landau theory. One theory models these materials using the condensation of Cooper pairs, and YBCO is a high-temperature example of them. Some of them act as perfect diamagnets that expel internal magnetic fields through the Meissner effect, and they are governed by BCS theory. For 10 points, name these materials that exhibit zero electrical resistance.
