The Meissner outcome shown by levitating a magnet earlier mentioned a cuprate superconductor, that's cooled by liquid nitrogen Beneath some situations, including very reduced temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" suggests previously mentioned 30 K). The key reason why for this is simply not understood, but https://reagentsusedindnaextracti59369.elbloglibre.com/39378365/the-fact-about-how-is-ceramic-made-that-no-one-is-suggesting
