The Meissner influence shown by levitating a magnet higher than a cuprate superconductor, which is cooled by liquid nitrogen Below some situations, for example exceptionally small temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" usually means above 30 K). The main reason for this is not comprehended, but https://silica-coated-magnetic-be82470.kylieblog.com/39773391/the-5-second-trick-for-silicon-carbide
