This phenomenon's Type I variety's electrons, if close to the Fermi level, will form Cooper pairs.
YBCO exhibits the high temperature variety of this phenomenon according to the 1987 Nobel Prize laureates, Johannes Bednorz and Karl Muller. The free energy of this phenomenon can be expressed in terms of psi in the Ginzburg-Landau theory. This phenomenon's Type I variety's electrons, if close to the Fermi level, will form Cooper pairs. Robert Ochsenfeld assisted in discovering the expulsion of the magnetic field during this phenomenon. Explained by the BCS theory and the Meissner effect, for 10 points, name this phenomenon characterized by the disappearance of electrical resistance in various solids.
