Figure 1

Crystal orientation and structure of (a) La0.7Sr0.3MnO3 (LSMO) (001) and (b) LSMO (110) films on Nb-doped SrTiO3 (STON) substrates. (c) Device structure for the photovoltaic effect measurements. (d) Temperature dependence of the resistivity for LSMO (001) and (110) films with different thicknesses deposited on Nb-free SrTiO3. The negative magnetoresistance is more pronounced for thinner films. (e) The relative change in resistivity (−Δρ/ρ0) as a function of temperature for the 3.2-nm-thick LSMO (110) film under 3- and 6-T fields.
