Abstract

Bi2Sr2CaCu2O8 (Bi-2212) superconducting nanowires are synthesized by the electrospinning method. Two different precursors were employed to grow the nanowires, a Pb-doped one and a Cu,Ca-enriched one. The granular polycrystalline character was confirmed by scanning electron microscopy and x-ray diffraction measurement. The magnetic and electric properties of the samples were investigated via SQUID magnetometry and four-probe resistance measurements. The superconducting transition temperatures of the two systems were found to be similar (Pb-doped 84 K, Cu,Ca-enriched 76 K), but the transition width and the onset of irreversibility were clearly different. The magnetization loops and the resistance data demonstrate that the Cu,Ca-enriched precursor yields samples with better superconducting properties.
