Title: Growth of electronically distinct manganite thin films by modulating cation stoichiometry

Abstract

Nd_1-xSr_xMnO₃ (NSMO) is a well-known manganite due to close connection between structure, transport, magnetism, and chemistry. Thus, it would be an ideal system to study modification of physical properties by external stimuli including control of stoichiometry in growth. In this work, we show that abrupt change of electronic and magnetic properties can be achieved by subtle change of oxygen partial pressure in pulsed laser deposition. Interestingly, the pressure indeed modulates cation stoichiometry. We clearly observed that the films grown at 150 mTorr and higher showed clear insulator to metal transition and stronger magnetism, commonly found in less hole doping, while the films grown at 130 mTorr and lower showed insulating behavior and weak magnetism. From soft x-ray spectroscopic methods, we clearly observed the compositional difference in those thin films. This result is further supported by scattering of lighter elements in high oxygen partial pressure but not by anion deficiency in growth.

Enhanced transport properties in La{sub x}MnO{sub 3-{delta}} thin films epitaxially grown on SrTiO{sub 3} substrates: The profound impact of the oxygen content

Journal Article Orgiani, P ; Maritato, L ; Aruta, C ; ... - Applied Physics Letters

We report on structural, magnetic, and transport properties of La{sub x}MnO{sub 3-{delta}} (LMO) thin films, epitaxially grown on SrTiO{sub 3} substrates by molecular beam epitaxy. Transport properties were investigated as a function of the La/Mn stoichiometry and the oxygen content. Optimal oxygenated LMO films (with stoichiometry ratio La/Mn=0.88) show a metal-insulator transitions temperature T{sub MI}{approx}387 K and magnetotransport similar to those found in strontium-doped La{sub 1-x}Sr{sub x}MnO{sub 3} manganites compounds. Also in presence of a La/Mn slight unbalance (namely, x=0.98), LMO films show a very high T{sub MI}{approx}370 K. However, LMO samples with La/Mn ratio larger than one, show severelymore »« less

Superexchange and iron valence control by off-stoichiometry in yttrium iron garnet thin films grown by pulsed laser deposition

Journal Article Dumont, Y ; Keller, N ; Popova, E ; ... - Journal of Applied Physics

Controlled off-stoichiometric single phase polycrystalline yttrium iron garnet (YIG) thin films have been grown by pulsed laser deposition, adjusting the oxygen partial pressure P{sub O2} between 5 and 400 mTorr. Atomic stoichiometry by RBS shows an oxygen deficiency for P{sub O2}<P{sub stoich} and iron and yttrium deficiency for P{sub O2}>P{sub stoich}. P{sub stoich}=30 mTorr refers to films showing magnetic and structural properties of the bulk stoichiometric YIG.

Enhancement of spin-lattice coupling in nanoengineered oxide films and heterostructures by laser MBE

Technical Report Xi, Xiaoxing

The objective of the proposed research is to investigate nanoengineered oxide films and multilayer structures that are predicted to show desirable properties. The main focus of the project is an atomic layer-by-layer laser MBE (ALL-Laser MBE ) technique that is superior to the conventional laser MBE in broadening the conditions for the synthesis of high quality nanoscale oxides and new designer materials. In ALL-Laser MBE, separate oxide targets are used instead of one compound target in the conventional laser MBE. The targets are switched back and forth in front of a UV laser beam as they are alternately ablated. Themore »« less

Cation non-stoichiometry in pulsed laser deposited Sr{sub 2+y}Fe{sub 1+x}Mo{sub 1-x}O₆ epitaxial films

Journal Article Meyer, T. L. ; Woodward, P. M., E-mail: woodward.55@osu.edu ; Dixit, M. ; ... - Journal of Applied Physics

Sr₂FeMoO₆ (SFMO) films were grown on SrTiO₃ (100)- and (111)-oriented substrates via pulsed laser deposition (PLD). In order to study the fundamental characteristics of deposition, films were grown in two different PLD chambers. In chamber I, the best films were grown with a relatively long substrate-to-target distance (89 mm), high substrate temperature (850 °C), and low pressure (50 mTorr) in a 95% Ar/5% H₂ atmosphere. Although X-ray diffraction (XRD) measurements indicate these films are single phase, Rutherford Backscattering (RBS) measurements reveal considerable non-stoichiometry, corresponding to a Sr₂Fe{sub 1–x}Mo{sub 1+x}O₆ composition with x≅0.2–0.3. This level of non-stoichiometry results in inferior magneticmore »« less

Oxygen off-stoichiometry and phase separation in EuO thin films

Journal Article Altendorf, S G ; Efimenko, A ; Oliana, V ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report on our study on the influence of the growth conditions on the europium/oxygen stoichiometry, morphology, magnetic properties, and electrical conductivity of EuO thin films. SQUID magnetometry and x-ray photoelectron spectroscopy were utilized as complementary techniques to determine the oxygen content of EuO{sub 1{+-}x} thin films grown by molecular beam epitaxy with and without the employment of the so-called Eu distillation process. We found indications for phase separation to occur in Eu-rich as well as in over-oxidized EuO for films grown at substrate temperatures below the Eu distillation temperature. Only a fraction of the excess Eu contributes to themore »« less
