Abstract

We have studied the fabrication of filamentary Ndl23 superconductor with high superconducting properties. The filamentary Nd123 precursor was prepared by the solution spinning method, through a homogeneous aqueous solution containing mixed acetates of Nd, Ba, Cu, poly (vinyl alcohol) and organic acids. The filamentary sample was partially melted at 990 °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 9.5 T at 77 K. The highest Jc value of 3.5×104 A/cm2 at 77 K and 0 T and more than 104 A/cm2 at 77 K and at 2 T was achieved for the filamentary Nd1.18Ba2.12Cu3.09Ox superconductor by controlling the oxygenation conditions.
