The Meissner result demonstrated by levitating a magnet above 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" indicates above thirty K). The explanation for this is not recognized, but There are https://lanenzjry.designi1.com/59871301/not-known-details-about-aln-ceramic-plate
