Effect of orbital ordering on anisotropy of transport property of manganites

Abstract The electrical conductivities for currents parallel and perpendicular to layers, respectively, in bilayered manganites with an orbital ordering are evaluated using Kubo formula. We adopt a two-orbital model with Jahn–Teller distortion for fully spin polarized ferromagnets. We find that the orbital ordering gives much smaller effect on the anisotropy of electrical conductivity than the potential barriers in bilayered structure.
