      abstract     = {The substitution in (Ba0.70Sr0.30)TiO3 thin films by the
                      rare-earth element dysprosium prepared at 1000°C by
                      chemical solution deposition on nickel foils was
                      investigated. The relatively large thermal budget applied
                      (via annealing temperature) is shown to enhance the
                      solubility of the Dy3+doping ion into the crystal lattice of
                      the perovskite films. Preference for B-site occupancy of
                      this amphoteric cation was further promoted by the addition
                      of BaO excess (1 $mol\%),$ which results in slightly larger
                      grains in the films as observed by scanning electron
                      microscopy. Despite this Ba-rich composition, the presence
                      of secondary phases in the thin films was not detected by
                      X-ray diffraction. Transmission electron microscopy revealed
                      no evidence for local segregation of Dy at grain boundaries,
                      neither the formation of NiO at the interface between the
                      film and the metal foil was observed. The substitution of
                      Ti4+ by Dy3+ leads to the formation of strong electron
                      acceptors in the system, which balance the number of ionized
                      oxygen vacancies arisen from the reductive crystallization
                      atmosphere used during processing. As a consequence, the
                      dielectric loss (tan σ) and leakage conduction measured in
                      the resulting thin-film capacitors were significantly
                      reduced with respect to nominally undoped samples. The
                      improvement of this capacitor feature, combined with the
                      relatively high permittivities obtained in the films
                      (490–530), shows the effectiveness of dysprosium doping
                      within a thin-film fabrication method for potential
                      application into the multilayer ceramic capacitor
                      technology.},
