Abstract
We reported on the effect of water on Bi-Pb-Sr-Ca-Cu-O system superconductor in the preceding report. This article reports the changes in various superconductivity characteristics when the superconductor is soaked in such organic solvents as ethyl alcohol, methyl alcohol, acetone and toluene since the organic solvent is often used to remove contaminants on the surface. As for critical temperature, critical current density and maximum magnetization, each of these surface values showed the tendency to decrease with soaking time. Therefore, it should be noted that the organic solvents affect the superconductor characteristics to some extent if they were used to remove the contamination on the surface.
