摘要： An oxide superconductor has a composition expressed by RE a Ba b Cu 3 O 7-x , where RE represents one rare earth or a combination of two or more of a rare earth, a satisfies 1.05 ‰¤ a ‰¤ 1.35, b satisfies 1.80 ‰¤ b ‰¤ 2.05, and x represents an amount of oxygen deficiency, and a non-superconducting phase having an outer diameter of 30 nm or less is included in a superconducting phase.
