Abstract

The filamentary (Nd, Sm, Eu, Gd)-Ba-Cu-O (LRE123) precursor was prepared by the solution spinning method, through a homogeneous aqueous solution containing mixed acetates of Nd, Sm, Eu, Gd, Ba, and Cu, poly(vinyl alcohol) and organic acids. The filamentary sample was partially melted at 980 °C in flowing 0.1% O2+Ar and oxygenated under various conditions. The transport critical current density (Jc) for the samples was examined in magnetic fields up to 10 T at 77 K. The highest Jc value of more than 1×104 A/cm2 at 77 K and 9 T was achieved for the filamentary Nd0.295Sm0.295Eu0.295Gd0.295Ba2.12Cu3.09Ox superconductors by controlling the oxygenation conditions.
