Ukutholakala kwei-copper oxideama-superconductors anezinga lokushisa elibalulekile elingu-Tc elingaphezu kuka-77K libonise amathemba angcono nakakhulu ama-superconductors, okuhlanganisa ama-superconductors e-perovskite oxide aqukethe izakhi zomhlaba eziyivelakancane, njenge-YBa2Cu3O7- δ。 (efushanisiwe njengesigaba esingu-123, i-YBaCuO noma i-YBCO) iwuhlobo olubalulekile lwezinga lokushisa eliphezulu superconducting impahla.Ikakhulukazi esindayo ezingavamile imihlaba, ezifanaGd, Dy, Ho, Er, Tm, futhiYb,ingashintsha kancane noma ngokuphelelei-yttrium yomhlaba engavamile (Y), okwenza uchungechunge lwe-Tc ephezuluumhlaba ongavamileizinto zokwakha ezinkulu (i-REBaCuO elula noma i-REBCO) enamandla amakhulu okuthuthuka.
Izinto ezingavamile ze-barium copper oxide superconducting zingenziwa zibe izinto ezisetshenziswayo ngobuningi besizinda esisodwa, ama-conductor amboziwe (amateyipu okushisa aphezulu esizukulwane sesibili), noma izinto zefilimu ezincanyana, ezisetshenziswa ngokulandelana kumadivayisi e-superconducting magnetic levitation kanye nozibuthe abangapheli, amandla kagesi aqinile. imishini, noma izinto zikagesi ezibuthakathaka.Ikakhulukazi lapho bebhekene nezinkinga zomhlaba wonke zamandla kanye nezindaba zemvelo, ososayensi babikezela ukuthi izinga lokushisa eliphakeme kakhulu lizongenisa inkathi entsha yokukhiqiza nokusabalalisa amandla.
I-Superconductivity ibhekisela eqinisweni lokuthi ngaphansi kwezimo ezithile, impahla ibhekwa njengokumelana ne-DC engu-zero kanye nezakhiwo eziphelele ze-diamagnetic.Lezi yizici ezimbili ezizimele, ezangaphambili ezaziwa nangokuthi yi-conductivity ephelele, kanti lena yakamuva yaziwa nangokuthi i-Meisner effect, okusho ukuthi i-magnetization iqeda ngokuphelele indawo kazibuthe yamandla kazibuthe, okuholela ekukhishweni ngokuphelele kwe-flux kazibuthe ingaphakathi lempahla.
