## Description

- description: "In the present study, critical current density (Jc) characteristics
    and uniformity of (Ba,Na)Fe2As2 wires and tapes fabricated by different methods
    and sheath materials are compared. Impurity-free high-quality polycrystalline
    powders were prepared by two different methods; direct reaction method and precursor
    method. By optimizing the firing temperature and holding time of precursors, we
    have succeeded in obtaining high quality precursor powders. In the case of wire
    drawing, a rotary swager with an automatic wire feeder is used to prevent sausaging.
    To further deform it into a tape form, cold press was used. In addition to the
    Jc characteristics of (Ba,Na)Fe2As2 wire and tapes, X-ray characterizations for
    the evaluation of texturing \r\nand uniformity are presented. Finally, a fine
    and long (Ba,Na)Fe2As2 wire is fabricated using Monel as an outer sheath material,
    and its characteristics are presented. "
