The Meissner outcome shown by levitating a magnet earlier mentioned a cuprate superconductor, and that is cooled by liquid nitrogen Underneath some ailments, such as very reduced temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" suggests previously mentioned 30 K). The reason for it's not comprehended, but There's https://silica-coated-magnetic-be05825.wonderkingwiki.com/2063635/nitreto_de_boro_hexagonal_an_overview
