Аннотация: This work is devoted to high-rate pulsed laser deposition of BaSnO3 -doped superconducting films on long buffered metal tape substrates with the use of pilot-scale equipment and common deposition conditions typical for commercial 2G hightemperature superconducting wire production at SuperOx Japan. BaSnO3 inclusions were found to grow as nanocolumns elongated along the vertical direction and having biaxial texture. With BaSnO3 doping, the angular dependence of critical current measured at 77 K became much more isotropic. At 77 K, the liftfactor ( Ic /Ic sf) values in BaSnO3 doped samples increased almost twice in 0.5–3 T magnetic field in perpendicular orientation; at the same time, the absolute critical current increased only by 10%. At 4.2 K, in 0.5–3 T perpendicular field, the absolute critical current in doped samples increased 1.8 times.
