The Meissner result demonstrated by levitating a magnet above a cuprate superconductor, which is 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 not comprehended, https://mag-beads14792.levitra-wiki.com/2007594/not_known_details_about_fused_silica
