The incorporation of nanoscaled pinning centers in superconducting (YBCO) films is one of the core topics to enhance the critical current density of coated conductors. The mixed double-perovskite Ba ₂ Y(Nb/Ta)O ₆ (BYNTO) can be grown in nanosized columns parallel to the YBCO -axis and in steplike patterns, making it customizable to meet specific working conditions . We compare a 1.6 $\upmu\text{m}$ thick film of pure YBCO and a similar film with additional 5 mol% of BYNTO, grown by pulsed laser deposition with a growth rate of 1.6 nm/s on chemically buffered biaxially textured Ni–5at.% W tape. Our doped sample shows nanosized BYNTO columns parallel to and plates in the -plane containing Y, Nb, and Ta. An improved homogeneity of the critical current density over the sample was evaluated from trapped field profiles measured with a scanning Hall probe microscope. The mean in the rolling direction of the tape is 1.8 MA/cm ² (77 K, self-field) and doubles the value of the undoped sample. Angular-dependent measurements of the critical current density, , show a decreased anisotropy of the doped film for various magnetic fields at 77 K and 64 K.
