The Meissner impact demonstrated by levitating a magnet above a cuprate superconductor, which happens to be cooled by liquid nitrogen Less than some disorders, for instance really minimal temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" usually means earlier mentioned 30 K). The reason for this is simply https://mylesspjey.fireblogz.com/70510419/not-known-details-about-aln
