The Meissner Outcome demonstrated by levitating a magnet earlier mentioned a cuprate superconductor, which can be cooled by liquid nitrogen Underneath some circumstances, for instance very very low temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" indicates earlier mentioned thirty K). The reason for this isn't comprehended, but https://dantehhhfv.idblogz.com/39571309/the-best-side-of-aluminiumoxid-keramik
