Kuwanikwa kwecopper oxidema superconductors ane tembiricha yakaoma Tc yakakwira kupfuura 77K yakaratidza zvirinani tarisiro ye superconductors, zvinosanganisira perovskite oxide superconductors ine zvisingawanzo zvinhu zvepasi, seYBa2Cu3O7- δ。 (yakapfupikiswa se 123 phase, YBaCuO kana YBCO) rudzi rwakakosha rwemhando yepamusoro-tembiricha. superconducting zvinhu. Kunyanya zvinorema zvisingawanzo pasi, sengeGd, Dy, Ho, Er, Tm,uyeYb,inogona kutsiva zvishoma kana zvachoseisingawanzo pasi yttrium (Y), kugadzira mutsara wepamusoro Tcrare pasisuperconducting zvinhu (zvakareruka REBaCuO kana REBCO) ine yakakura budiriro mukana.
Rare earth barium copper oxide superconducting zvinhu zvinogona kugadzirwa kuita single domain yakawanda zvinhu, coated conductors (yechipiri-chizvarwa chepamusoro-temperature superconducting matepi), kana zvitete zvemufirimu zvinhu, izvo zvinoshandiswa zvakateerana mu superconducting magineti levitation zvishandiso uye magineti asingagumi, simba remagetsi rakasimba. michina, kana midziyo yemagetsi isina simba. Kunyanya pakatarisana nedambudziko resimba repasi rose uye nyaya dzezvakatipoteredza, masayendisiti anofanotaura kuti kutonhora kwepamusoro-soro kuchaunza nguva itsva yekugadzira simba uye kugovera.
Superconductivity inoreva chokwadi chekuti pasi pemamwe mamiriro, chinhu chinonzi chine zero DC kuramba uye yakakwana diamagnetic zvivakwa. Aya ndiwo maviri akazvimirira ega zvivakwa, iyo yaimbozivikanwa seyakazara conductivity, uye iyo yekupedzisira inozivikanwawo seMeisner athari, zvinoreva kuti iyo magnetization inobvisa zvachose iyo magineti yesimba remagineti, zvichikonzera kubviswa zvachose kwemagineti kubva. mukati mezvinhu.
