  1. 79. M2Or1B-01: [Invited] Combination of thermodynamic and pinning optimization routes for enhancing Jc
    Prof. Masashi Miura (Seikei University)
    11/07/2023, 09:30
    Invited Oral

    For superconducting magnets and other applications, enhancing the critical current density (Jc) is required. There are several possible approaches for enhancing Jc in REBa2Cu3Oy coated conductors (CCs); one is by introducing and tailoring pinning centers to immobilize vortices. Another is by enhancing the thermodynamic critical field...

  2. 592. M2Or1B-02: [Invited] Methods to enhance and tune vortex pinning in coated conductors
    Dr Leonardo Civale (Los Alamos National Laboratory (Retired))

    Invited Oral

    At liquid He temperatures and low magnetic fields, ReBCO films and coated conductors (CC) can have extremely large critical current densities ($J_c$), in excess to 100 MA/cm$^2$, the highest among known superconductors, making CCs very attractive for power applications. However, $J_c$ tends to decrease sharply as either $T$ or $H$ increases, thus additional pinning centers must be introduced...

  3. 497. M2Or1B-03: [Invited] Ca-repaired BaZrO3 nanorods/YBa2Cu3O7-x interface for enhanced pinning in YBa2Cu3O7-x nanocomposites with 2-8% BaZrO3 doping

    Invited Oral

    C-axis aligned BaZrO3 (BZO) nanorods formed via strain-mediated self-assembly in BZO-doped YaBa2Cu3O7-x (BZO/YBCO) nanocomposite films can provide strong pinning to the quantized magnetic vortices. While the strain initiated from the BZO/YBCO lattice mismatch plays a critical role in nucleation and evolution of the BZO nanorods, it also leads to a highly defective BZO/YBCO interface and hence...

  4. 467. M2Or1B-04: [Invited] Understanding In-Field Performance of REBCO Conductor with Artificial Pinning Centers by Scanning Raman Spectroscopy and 2D-XRD
    Goran Majkic (University of Houston)
    11/07/2023, 10:40
    Invited Oral

    We present progress in development and understanding of the in-field performance of REBCO conductor with Artificial Pinning Centers (APCs) in the form of BMO nanorods (M = Zr, Hf, Sn, etc.). First, we present TEM findings on in-plane strain accommodation mechanisms between BMO and REBCO matrix, where the interfaces have been found to never be fully coherent, and that the degree of...
