| Outline of Final Research Achievements |
Based on TDGL simulations of critical current density Jc and unique flux-pinning modeling, optimum artificial pinning centers (APCs) of REBa2Cu3Ox (REBCO) superconducting films have been extensively studied. REBCO films were deposited on single crystal substrates or IBAD-MgO substrates by using PLD method which is available for making nanocomposite films. Several deposition techniques such as mixed target, low temperature growth and so on were used for controlling size and spatial distribution of APCs. Very high global pinning force density of 32 GN/m3 at 77 K and 1800 GN/m3 at 4.2 K were successfully attained, and simultaneously zero-field Jc might reach 30% of theoretical limit.
