Objects with this property have a characteristic coherence length and London penetration depth, and can be used in SQUID magnetometers.
Objects with this property have a characteristic coherence length and London penetration depth, and can be used in SQUID magnetometers. It can be described by Ginzburg-Landau theory, and a perovskite-based compound can maintain this property at a temperature above 77K, and is called (*) YBCO. The Type I of this phenomenon is explained as the condensation of electrons into Cooper pairs by BCS theory and this effect causes the expulsion of magnetic fields in the Meissner effect, which can allow materials with this property to levitate. For 10 points, materials lowered below their critical temperature have what property in which there is no resistance?
