SOURCE MATERIAL SOLUTION FOR FORMING OXIDE SUPERCONDUCTOR

摘要

A source material solution for forming an oxide superconductor is provided, the source material solution being used for forming on a substrate an RE 123 oxide superconductor into which flux pinning points are introduced, using a coating-pyrolysis process. Nanoparticles of a predetermined amount for forming pinning points are dispersed in the solution in which an organometallic compound is dissolved for forming the oxide superconductor. The nanoparticles have a particle size of 5 to 100 nm. The organometallic compound is an organometallic compound containing no fluorine. Accordingly, even in an FF-MOD process, the material for pins can easily be added, a treatment for thermally decomposing a metal complex and a heat treatment for generating a pin compound are unnecessary, and the particle size of the pins can suitably be controlled.
