Ubuvumbuzi bwaokiside y'umuringasuperconductors ifite ubushyuhe bukomeye Tc irenze 77K yerekanye ibyiringiro byiza kubidasanzwe, harimo na perovskite oxide superconductor irimo ibintu bidasanzwe byubutaka, nka YBa2Cu3O7- δ。 (mu magambo ahinnye yicyiciro cya 123, YBaCuO cyangwa YBCO) nubwoko bwingenzi bwubushyuhe bwo hejuru ibikoresho birenze urugero.Cyane cyane isi idasanzwe iremereye, nkaGd, Dy, Ho, Er, Tm, naYb,irashobora gusimbuza igice cyangwa rwoseisi idasanzwe yttrium (Y), gukora urukurikirane rwa Tc ndendeisi idasanzweibikoresho birenze urugero (byoroshye REBaCuO cyangwa REBCO) bifite imbaraga zikomeye ziterambere.
Ntibisanzwe isi barium umuringa wa oxyde superconducting irashobora gukorwa mubikoresho byinshi bya domaine, ibyuma bitwikiriye (kaseti yo mu gisekuru cya kabiri yubushyuhe bwo hejuru cyane), cyangwa ibikoresho bya firime byoroheje, bikoreshwa mugukoresha ibikoresho birenze urugero bya rukuruzi hamwe na magnesi zihoraho, ingufu zikomeye z'amashanyarazi. imashini, cyangwa ibikoresho bya elegitoroniki bidakomeye.By'umwihariko imbere y’ibibazo by’ingufu ku isi n’ibibazo by’ibidukikije, abahanga bavuga ko ubushyuhe bukabije bw’ubushyuhe bwo hejuru buzatangiza ibihe bishya byo kubyara amashanyarazi no gukwirakwiza.
Ububasha bwikirenga bivuga ko mubihe bimwe na bimwe, ibintu bifatwa nkibishobora kurwanya zeru DC hamwe na diamagnetic yuzuye.Iyi ni imitungo ibiri yigenga, iyambere izwi kandi nka conducivite yuzuye, naho iyindi izwi kwizina rya Meisner, bivuze ko magnetisiyonike ihagarika burundu imitungo ya magneti yimbaraga za magnetique, bikavamo gukuraho burundu flux ya magnetiki kuva imbere y'ibikoresho.
