The Meissner Impact shown by levitating a magnet over a cuprate superconductor, which happens to be cooled by liquid nitrogen Less than some disorders, for instance particularly lower temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" means higher than thirty K). The explanation for this is not recognized, https://isolationofultratraceamou92579.wssblogs.com/39096858/examine-this-report-on-aluminum-nitride-ceramic
