Title: Density-Functional-Theory Modeling of Cation Diffusion in Bulk ${La}_{1 - x} {Sr}_{x} {MnO}_{3 \pm δ}$ ( $x = 0.0 - 0.25$ ) for Solid-Oxide Fuel-Cell Cathodes

Abstract

In this work, the A - and B -site cation migration pathways involving defect complexes in bulk La_1-xSr_xMnO_3±δ (LSM) at x = 0.0-0.25 are investigated based on density-functional-theory modeling for solid-oxide fuel-cell (SOFC) cathode applications. We propose a dominant A -site cation migration mechanism which involves an A -site cation (e.g., La$$x\atop{A}$$) V_A"' of a V_A"' -V_B"' cluster, where La$$x\atop{A}$$, V_A"' and V_B"' are La³⁺, A-site vacancy, and B-site vacancy in bulk LSM, respectively, and V_A"' -V_B"' is the first nearest-neighbor V_A"' and V_B"' pair. This hop exhibits an approximately 1.6-eV migration barrier as compared to approximately 2.9 eV of the La$$x\atop{A}$$ hop into a V_A"'. This decrease in the cation migration barrier is attributed to the presence of the V_B"' relieving the electrostatic repulsion and steric constraints to the migrating A-site cations in the transition-state image configurations.

Electrical transport properties of Ti-doped Fe $_{2}$ $O_{3}$ (0001) epitaxial films

Journal Article Zhao, B. ; Kaspar, T. C. ; Droubay, T. C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

The electrical transport properties for compositionally and structurally well-defined epitaxial α-(TixFe1-x)2O3(0001) films have been investigated for x ≤ 0.09. All films were grown by oxygen plasma-assisted molecular beam epitaxy using two different growth rates: 0.05–0.06 Å/s and 0.22–0.24 Å/s. Despite no detectable difference in cation valence and structural properties, films grown at the lower rate were highly resistive whereas those grown at the higher rate were semiconducting (ρ = ~1 Ω · cm at 25 °C). Hall effect measurements reveal carrier concentrations between 1019 and 1020 cm-3 at room temperature and mobilities in the range of 0.1 to 0.6 cm2/Vmore »« less

Ferromagnetism and superconductivity in CeFeAs $_{1 - x}$ $P_{x}$ O ( $0 \leq x \leq 40 %$ )

Journal Article Jesche, A. ; Förster, T. ; Spehling, J. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report on superconductivity in CeFeAs_1-xP_xO and the possible coexistence with Ce ferromagnetism (FM) in a small homogeneity range around x=30% with ordering temperatures of T_SC≅T_C≅4 K. The antiferromagnetic (AFM) ordering temperature of Fe at this critical concentration is suppressed to Tmore »« less

${}^{77}{Se}$ NMR investigation of the $K_{x}$ Fe $_{2 - y}$ Se $_{2}$ high- $T_{c}$ superconductor ( $T_{c} = 33$ K)

Journal Article Torchetti, D. A. ; Fu, M. ; Christensen, D. C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report comprehensive 77 Se NMR measurements on a single crystalline sample of the recently discovered FeSe-based high-temperature superconductor K x Fe 2 - y Se 2 ( T c = 33 K) in a broad temperature range up to 290 K. Despite deviations from the stoichiometric KFe 2 Se 2 composition, we observed 77 Se NMR line shapes as narrow as 4.5 kHz under a magnetic field applied along the crystal c axis, and found no evidence for co-existence of magnetic order with superconductivity. On the other hand, the 77 Se NMR line shape splits into two peaks withmore »« less

Magnetic-Field Tuning of Light-Induced Superconductivity in Striped ${La}_{2 - x} {Ba}_{x} {CuO}_{4}$ [Magnetic-Field Tuning of Photo-Induced Superconductivity in Striped ${La}_{2 - x} {Ba}_{x} {CuO}_{4}$ ]

Journal Article Nicoletti, Daniele ; Fu, D. ; Mehio, O. ; ... - Physical Review Letters

Optical excitation of stripe-ordered La_2–xBa_xCuO₄ has been shown to transiently enhance superconducting tunneling between the CuO₂ planes. This effect was revealed by a blueshift, or by the appearance of a Josephson plasma resonance in the terahertz-frequency optical properties. Here, we show that this photoinduced state can be strengthened by the application of high external magnetic fields oriented along the c axis. For a 7 T field, we observe up to a tenfold enhancement in the transient interlayer phase correlation length, accompanied by a twofold increase in the relaxation time of the photoinduced state. These observations are highly surprising, since staticmore »« less
