Abstract

The filaments have been prepared by dry spinning through a homogeneous aqueous solution containing mixed acetates of Y, Ba, and Cu, polyvinyl alcohol, and organic acids. After spinning, the filament was sintered or partially melted to generate the superconducting phase. Magnetization properties of the filaments are examined. Since solution spinning introduces a fine flux pinning center into the superconducting phase, such as at elemental level, a significantly improved Jc value estimated from the magnetization curves and field dependence of the Jc have been achieved in the solution-spun filament. The phase decomposition from the 124 phase to the 123 phase and partial melting result in an enhancement of flux pinning.
