“…For this purpose, we have synthesized by pulsed laser deposition Nd2-xCexCuO4+δ/SrTiO3 epitaxial films with optimal oxygen content δ=0 and x = 0.135, 0.145 and 0.15 of three types [26]: I -films with standard orientation (001) where the c-axis of the Nd2-xCexCuO4+δ lattice is perpendicular to the SrTiO3 substrate plane; to measure the longitudinal ρxx ab and Hall ρxy ab resistivities in CuO2 layers. II-films (1ī0) where the c-axis of the Nd2-xCexCuO4+δ lattice is directed along the long side of the SrTiO3 substrate; to measure the longitudinal ρxx c resistivity between (across) CuO2 layers.…”
