Daahfurkiinaxaas oksaydhkontaroolayaasha sare ee heerkulka muhiimka ah ee Tc ka sarreeya 77K ayaa muujiyay xitaa rajooyin wanaagsan oo loogu talagalay kontaroolayaasha sare, oo ay ku jiraan perovskite oxide superconductors oo ay ku jiraan walxo dhul dhif ah, sida YBa2Cu3O7-δ。 (oo loo soo gaabiyo 123 wajiga, YBaCuO ama YBCO) waa nooc muhiim ah oo heerkul sare ah wax ka sarreeya.Gaar ahaan dhulyo dhif ah oo culus, sidaGd, Dy, Ho, Er, TmiyoYb,qayb ahaan ama gebi ahaanba beddeli karaDhulka dhifka ah yttrium (Y), samaynta taxane sare oo Tcdhul dhif ahagab tayo sare leh (REBaCuO fudud ama REBCO) oo leh awood horumarineed oo weyn.
Qalabka naadirka ah ee barium copper oxide superconducting waxa laga samayn karaa hal shay oo bulk ah, kirishbooyada dahaarka leh (cajalad heerkul sare leh oo jiilka labaad ah), ama walxaha filimka khafiifka ah, kuwaas oo loo isticmaalo kor u qaadida qalabka magnetic levitation iyo magnets joogto ah, awood koronto oo xoog leh. mishiinada, ama qalabka korantada ee daciifka ah.Gaar ahaan marka la eego dhibaatooyinka tamarta adduunka iyo arrimaha deegaanka, saynisyahannadu waxay saadaaliyaan in heerkulka sare ee heerkulka sare uu keeni doono xilli cusub oo koronto iyo qaybin.
Dhaqdhaqaaqa sare waxa loola jeedaa in xaaladaha qaarkood, shay loo tixgaliyo in aanu lahayn iska caabin DC eber ah oo dhammaystiran sifooyinka diamagnetic.Kuwani waa laba siyood oo madax-bannaan, kii hore oo sidoo kale loo yaqaannaa conductivity dhamaystiran, iyo kan dambe oo sidoo kale loo yaqaan saamaynta Meisner, taas oo macnaheedu yahay in magnetization-ku si buuxda u dhimayo hantida magnetic ee xoogga magnetic, taasoo keentay in gebi ahaanba laga saaro qulqulka magnetic gudaha maaddada.
