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 se123 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.
Kashoma pasi barium copper oxide superconducting zvinhu zvinogona kugadzirwa kuita imwechete 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 mukutarisana nematambudziko epasi rose emagetsi uye nyaya dzezvakatipoteredza, masayendisiti anofanotaura kuti kutonhora kwakanyanya kwepamusoro kuchaunza nguva itsva yekugadzira magetsi uye kugovera.
Superconductivity inoreva chokwadi chekuti pasi pemamwe mamiriro, chinhu chinonzi chine zero DC kuramba uye yakazara diamagnetic zvivakwa.Aya ndiwo maviri akazvimirira ega zvivakwa, iyo yaimbozivikanwa seyakazara conductivity, uye iyo yekupedzisira inozivikanwawo seMeisner athari, zvinoreva kuti iyo magnetization inobvisa zvachose simba remagineti resimba remagineti, zvichikonzera kubviswa zvachose kwemagnetic flux kubva. mukati mezvinhu.
