✦ Synopsis

We report on the fabrication and superconducting transport properties of superconducting fibers with typical cross-sectional areas of 10 2 to 10 3 JLm 2 made using the polymer-metal precursor (PMC) technique. These samples show superconducting properties similar to good quality bulk polycrystalline pellets, with Jc (77K) ~10 3 A/cm 2 and J c ( 4K) ~10 4 A/cm 2 • Magnetic field measurements show that the fiber's superconducting transport properties are dominated by weak links between grains, as in bulk polycrystalline materials.
