The Meissner result demonstrated by levitating a magnet above a cuprate superconductor, that is cooled by liquid nitrogen Under some conditions, which include particularly lower temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" means higher than thirty K). The main reason for this is not comprehended, but there https://rna-beads15825.sharebyblog.com/39076355/not-known-details-about-aln-ceramic-plate
