Summary

Description
English: High-temperature superconductivity

- Hight-temperature superconductors (HTS) become superconductive at a temperature close to the temperature of boiling of liquid nitrogen (LNT) (but always higher than this). The materials belong to the class of ceramics; the composition is formally oxides of barium, yttrium/lanthanum and copper. Part of the copper is trivalent. When a strong magnet (e.g. neodymium one) is placed over the superconductor below the critical temperature, the magnet induces circular current which by itself imposes a magnetic field around the superconductor, with an opposite orientation of that of the permanent magnet used. As a result, the magnet levitates above the superconductor (Meisner effect).

Македонски: Високотемпературна суперспроводливост

- Високотемпературните спроводници стануваат суперспроводливи веќе при температура на вриење на течен азот (повисока од оваа). Се работи за керамички материјали на база на оксиди од бариум, итриум/лантан и бакар. Дел од бакарот е со оксидационен број +3. Кога силен (на пр. неодиумски) магнет ќе се постави врз високотемпературниот суперспроводник, магнетот индуцира кружна струја во суперспроводникот која, од своја страна, доведува до постоење на магнетно поле околу сиперспроводникот што е спротивно насочено од она на магнетот. Резултатот е лебдење на магнетот над суперспроводникот (Мајснеров ефект).
