Abstract

We present a resonant x-ray scattering study of the octahedral tilt order between 50 K and 310 K in La{sub 7/8}Sr{sub 1/8}MnO{sub 3}. At the La L{sub II}-edge, the resonant (300) reflection probes cooperative tilts of the MnO{sub 6} octahedra in this material, as verified by a model caclulation as well as a LDA+U study. The investigation of the octahedral tilts as a function of temperature and the comparison to the lattice parameters, the magnetization and the superlattice reflections related to charge and/or orbital order reveal an intimate coupling between electronic and tilt degrees of freedom in La{sub 7/8}Sr{sub 1/8}MnO{sub 3}.

The electronic structure of La{sub 0.66}Ca{sub 0.33}MnO{sub 3} and La{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} studied by angle resolved photoemission

Liu, Rong ; Tonjes, W. C. ; Olson, C. G. ; ... - Journal of Applied Physics

We report angle resolved photoemission studies of La{sub 0.66}Ca{sub 0.33}MnO{sub 3} and La{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} using single crystal samples. The Mn 3p-3d resonance photoemission data of La{sub 0.66}Ca{sub 0.33}MnO{sub 3} show that the states at 2.5 eV binding energy have predominantly Mn 3d character, qualitatively consistent with the predictions of local spin density approximation calculations except for a 1 eV shift toward higher binding energy. Band dispersions are observed in the normal emission data. The spectra of La{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} show well defined features and strong matrix element effects, indicating excellent surface quality.

Non-local spin injection effects in coplanar La{sub 0.7}Sr{sub 0.3}MnO{sub 3}/Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}/ La{sub 0.7}Sr{sub 0.3}MnO{sub 3} tri-layer

Joseph, D. Paul ; Lin, J. G., E-mail: jglin@ntu.edu.tw - AIP Conference Proceedings

Non-local electrical properties of pulsed laser deposited La{sub 0.7}Sr{sub 0.3}MnO{sub 3}/Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}/La{sub 0.7}Sr{sub 0.3}MnO{sub 3} (L-B-L) coplanar tri-layer is investigated under different wiring configurations. Long range super-current of Bi-2212 penetrating into LSMO is dependent on geometry of spin injection. From qualitative analysis of structural, magnetic and electrical data, long range super-current is suggested to pass through domain walls and/or grain boundaries of LSMO.

Thickness dependent electronic structure of La{sub 0.6}Sr{sub 0.4}MnO{sub 3} layer in SrTiO{sub 3}/La{sub 0.6}Sr{sub 0.4}MnO{sub 3}/SrTiO{sub 3} heterostructures studied by hard x-ray photoemission spectroscopy

Yoshimatsu, K. ; Horiba, K. ; Kumigashira, H. ; ... - Applied Physics Letters

The authors have investigated changes in the electronic structures of digitally controlled La{sub 0.6}Sr{sub 0.4}MnO{sub 3} (LSMO) layers sandwiched between SrTiO{sub 3} as a function of LSMO layer thickness in terms of hard x-ray photoemission spectroscopy (HX-PES). The HX-PES spectra show the evolution of Mn 3d derived states near the Fermi level and the occurrence of metal-insulator transition at 8 ML. The detailed analysis for the thickness dependent HX-PES spectra reveals the existence of the less conducting and nonmagnetic transition layer with a film thickness of about 4 ML in the interface region owing to significant interaction through the interface.

Effect of superconducting spacer layer thickness on magneto-transport and magnetic properties of La{sub 0.7}Sr{sub 0.3}MnO{sub 3}/YBa{sub 2}Cu{sub 3}O{sub 7}/La{sub 0.7}Sr{sub 0.3}MnO{sub 3} heterostructures

We have studied the magneto-transport and magnetic properties of LSMO/YBCO/LSMO trilayers on LaAlO{sub 3} (001) substrate, deposited using pulsed laser deposition technique. From x-ray diffraction measurements, it is confirmed that the grown trilayer films are single phase natured. The temperature dependent resistivity shows a metallic behavior below 350 K. At low temperature from resistivity fitted data, we observe that electron-electron, electron-phonon, and electron-magnon interactions are the main factors for scattering of carriers. The ferromagnetic LSMO layers suppress the critical temperature of YBCO spacer layer. We observe maximum magnetoresistance value ∼49% at 250 K for LSMO(200 nm)/YBCO(50 nm)/LSMO(200 nm) trilayer. Magnetization measurements reveal that at roommore »« less

Growth and properties of La{sub 0.7}Sr{sub 0.3}MnO{sub 3}/YBa{sub 2}Cu{sub 3}O{sub 7−δ}/La{sub 0.7}Sr{sub 0.3}MnO{sub 3} epitaxial trilayer films

Sharma, Minaxi, E-mail: meenanith@gmail.com ; Kumar, Arvind ; Sharma, K. K. ; ... - AIP Conference Proceedings

We report the growth and properties of La{sub 0.7}Sr{sub 0.3}MnO{sub 3}/YBa{sub 2}Cu{sub 3}O{sub 7−δ}/La{sub 0.7}Sr{sub 0.3}MnO{sub 3} LSMO/YBCO/LSMO epitaxial trilayer films, fabricated on SrTiO{sub 3} substrate using pulsed laser deposition technique. From x-ray diffraction and high resolution x-ray diffraction measurements, it is confirmed that the grown trilayered films are single phase and epitaxial in nature. Magneto-transport and magnetic properties are found to be dependent on the thickness of YBCO spacer layer. We infer that for fixed thickness of top and bottom LSMO layers, superconductivity is completely suppressed. At 100 K, the hysteresis loops reveal the ferromagnetic signature of trilayered film.more »« less
