چکیده انگلیسی
The relation between the c-axis lattice parameter of REBa2Cu3O7âδ (REBCO and REâ¯=â¯Gd, Y) superconductors with 25â¯mol.% Zr addition and the critical current density (Jc) was determined at (77â¯K, 0  T), (30â¯K, 3 T (B||c)), and (30â¯K, 9 T (B||c)). In this work, heavily doped Zr-added REBCO films with the thickness of 0.9â¯Âµm were fabricated by metal organic chemical vapor deposition (MOCVD) using a roll-to roll process. An increase in REBCO c-axis lattice parameter and a decrease in elastic mismatch strain relative to self-assembled BZO nanocolumns were observed with increasing (Baâ¯+â¯Zr)/Cu content. The optimum c-axis lattice parameter for achieving the highest Jc in magnetic field was found to be temperature and field dependent, with optimum values of 11.74, 11.76 and 11.78â¯Ã
at (77â¯K, 0 T), (30â¯K, 3 T (B||c)), and (30â¯K, 9 T (B||c)), respectively.
