The Meissner influence demonstrated by levitating a magnet over a cuprate superconductor, that is cooled by liquid nitrogen Under some conditions, which include exceptionally very low temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" means higher than 30 K). The main reason for this is not comprehended, but https://superparamagneticbeads05825.oblogation.com/38108506/the-ultimate-guide-to-radiateur-ceramique
