The Meissner impact demonstrated by levitating a magnet above a cuprate superconductor, which is 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, but There https://gregorybvohz.yomoblog.com/46223999/carbure-de-silicium-an-overview
