摘要： PROBLEM TO BE SOLVED: To obtain an Re-based oxide superconducting wire that is excellent in applied field angle dependence by finely dispersing flux pinning points in a superconductor. SOLUTION: A mixed solution is made of an organometallic complex solution, including a metal element constituting an Re-based superconductor with reduced Ba concentration, and an organometallic complex solution including at least one of metals having a large affinity for Ba and selected from among Zr, Ce, Sn, or Ti. The mixed solution is applied on an interlayer of a composite substrate. Then, the composite substrate is burned and Zr-containing oxide particles (flux pinning points) are artificially and finely dispersed. Consequently, it is possible to significantly improve the applied field angle dependence of Jc (Jc, min /Jc, max ). COPYRIGHT: (C)2009,JPO&INPIT
