A London penetration depth is the distance a magnetic field penetrates in a material of this type which John Schrieffer partially explained.
The Kondo effect gives a key characteristic that these materials. A London penetration depth is the distance a magnetic field penetrates in a material of this type which John Schrieffer partially explained. Their Type II variety contain Abrikosov vortices, and their defining characteristic can be modeled using Landau-Ginzberg theory. They exhibit the Meissner Effect, contain Cooper Pairs, and are subject to BCS theory.  YBCO is an example of one found at high temperatures. For ten points, name these substances that have 0 resistance.
