<p><P>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. <P>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,<SB>min</SB>/Jc,<SB>max</SB>). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
