RE-123-BASED SUPERCONDUCTING WIRE AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
<p>An RE123-based superconducting wire includes a base material, an intermediate layer formed on the base material, and an oxide superconducting layer which is formed on the intermediate layer and includes an oxide superconductor having a composition formula represented by RE 1 Ba 2 Cu 3 O 7-´ (RE represents one or two or more rare earth elements), in which the oxide superconducting layer includes 0.5 to 10 mol% of a Hf-including compound dispersed in the oxide superconducting layer as an artificial pinning center, a film thickness d of the oxide superconducting layer is d>1 µm, and a current characteristic of J cd /J cl ‰¥0.9 (J cl represents a critical current density when the thickness of the oxide superconducting layer is 1 µm, and J cd represents the critical current density when the thickness of the oxide superconducting layer is d µm) is satisfied.</p> |
