  1. 373. [Invited] Enhanced pinning in heavily-doped REBCO coated conductors
    Dr Xiao-Fen Li (University of Houston)
    12/07/2017, 14:00
    Invited Oral Presentation

    Critical current density over 20 MA/cm^2 has been achieved at 30 K, 3 T (B||c) in RE-Ba-Cu-O (REBCO, RE=rare earth) coated conductors made by metal organic chemical vapor deposition (MOCVD) with addition of Zr at levels as high as 25 mol.%. Flux pinning force over 1.7 TNm^-3 has also been achieved at 4.2 K. We have observed a strong dependence of the critical current performance and the...

  2. 528. [Invited] Enhancing Flux Pinning of Y-Ba-Cu-O Superconducting Thin Films at ≤ 30 K and H ≥ 3 T
    Mrs Mary Ann Sebastian (U.S. Air Force Research Laboratory)
    12/07/2017, 14:30
    Invited Oral Presentation

    The addition of many types of defects to YBa2Cu3O7-z (Y-Ba-Cu-O or YBCO) superconductor thin films have been studied by many groups world-wide, to enhance flux pinning and strongly increase critical current densities (Jcs). Since the first publications of this field in 2003 and 2004, over 6,200 citations have been listed for the subfield ‘flux pinning YBCO’, and the subfield ‘flux pinning’...

  3. 426. [Invited] Modeling and simulation of flux pinning of REBCO thin films with artificial pinning centers
    Prof. Kaname Matsumoto (Kyushu Institute of Technology)
    12/07/2017, 15:00
    Invited Oral Presentation

    Along with the progress of coated conductors, research to introduce artificial pinning centers into REBCO superconducting films is actively underway. Nanorods and nanoparticles or their hybrid structures were tried as artificial pinning centers, and, as a result, large global pinning forces of 20-30 GN/m3 at 77 K and values exceeding 1TN/m3 at 4.2 K have been realized. However, it is still...

  4. 436. [Invited] Correlated and random pinning behaviors in Sm123 tapes with nanorods
    Prof. Satoshi Awaji (Tohoku University)
    12/07/2017, 15:30
    Invited Oral Presentation

    An introduction of artificial pinning centers (APC) is one of the key techniques to improve a large anisotropy in critical current density $J_c$ REBa$_2$Cu$_3$O$_y$ (RE123, RE: Y and rare earth) tapes. The APC technique is utilized in the practical RE123 coated conductors, recently. One of the most promising APCs is a BaMO$_3$ (M; Zr, Sn, Hf, etc) nanorod, which is a nano-scaled...
