Kupezeka kwa copper oxide superconductors ndi kutentha kwambiri kwa Tc kuposa 77K kwawonetsa chiyembekezo chabwinoko cha ma superconductors, kuphatikiza ma perovskite oxide superconductors okhala ndi zinthu zapadziko lapansi, monga YBa2Cu3O7- δ。 (yofupikitsidwa ngati 123 gawo, YBaCuO kapena YBCO) ndi chopanda pake. ...
