      abstract     = {We fabricated high-quality c-axis-oriented epitaxial
                      YBa2Cu3O7−x films with $15\%$ of the yttrium atoms
                      replaced by terbium (YTBCO) and studied their electrical
                      properties. The Tb substitution reduced the charge carrier
                      density, resulting in increased resistivity and decreased
                      critical current density compared to pure YBa2Cu3O7−x
                      films. The electrical properties of the YTBCO films showed
                      an in-plane anisotropy in both the superconducting and
                      normal states that, together with the XRD data, provided
                      evidence for, at least, a partially twin-free film.
                      Unexpectedly, the resistive transition of the bridges also
                      demonstrated the in-plane anisotropy that could be explained
                      within the framework of Tinkham’s model of resistive
                      transition and the Berezinskii–Kosterlitz–Thouless (BKT)
                      model, depending on the sample parameters. Measurements of
                      the differential resistance in the temperature range of the
                      resistive transition confirmed the occurrence of the BKT
                      transition in the YTBCO bridges. Therefore, we consider the
                      YTBCO films to be a promising platform for both the
                      fabrication of devices with high kinetic inductance and
                      fundamental research on the BKT transition in cuprate
                      superconductors.},
