Growth of Thick BaZrO3-doped YBa2Cu3O7-δ Films with High Critical Currents in High Applied Magnetic Fields

Conference ·
OSTI ID:961759

High quality, thick YBa2Cu3O7- (YBCO) films with splayed self-assembly of BaZrO3 insulating nanodot columns were epitaxially grown on short pieces of technically important textured metallic templates, ion-beam-assisted deposition (IBAD) MgO substrates by pulsed laser deposition. Variations in superconducting and microstructual properties are observed in the samples grown at different substrate temperatures of 790-810oC. At optimized substrate temperature ranges of 790 and 800oC, the samples were measured to have large self-field Ic of 670-787 A/cm at 77 K and minimum Ic of 353-392 A/cm with respect to all angles at 65 K, 3 T respectively.
