Abstract

Provided is a method of forming a superconducting wire, the method including forming a superconducting precursor film on a substrate, the super conducting precursor film containing Re, Ba, and Cu having a composition in which Ba is poor and Cu is rich compared to stoichiometric ReBCO(GdBaCuO, 0≤y≤6, Re: Rare earth element), heating the substrate to melt the superconducting precursor film, providing an oxygen gas having an oxygen partial pressure of about 10 mTorr to about 200 mTorr on the molten superconducting precursor film to form a superconducting layer including an epitaxial superconductor biaxially aligned only in the c-axis direction perpendicular to the substrate, and cooling the substrate.
