The Meissner Impact demonstrated by levitating a magnet above a cuprate superconductor, which happens to be cooled by liquid nitrogen Less than some disorders, for instance particularly lower temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" means earlier mentioned 30 K).
