Abstract :
High quality, thick YBa2Cu3O7-delta (YBCO) films with splayed, self-assembled BaZrO3 insulating nanodot columns were epitaxially grown by pulsed laser deposition on short pieces of ion-beam-assisted deposition (IBAD) MgO substrate. Variations in superconducting and microstructural properties were observed for samples grown at different substrate temperatures between 790 and 810degC. At substrate temperatures between 790 and 800degC, samples were measured to have large self-field I c of 670-787 A/cm at 77 K and minimum I c of 353-392 A/cm for all angles at 65 K, 3 T.
