The Meissner Influence demonstrated by levitating a magnet previously mentioned a cuprate superconductor, which is cooled by liquid nitrogen Beneath some disorders, for example exceptionally minimal temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" usually means over 30 K). The rationale for it's not recognized, but There's two https://travisnlgbv.cosmicwiki.com/2054981/nitreto_de_boro_hexagonal_an_overview
