Phonons reflect dynamic spin-state order in LaCoO
Alsu Ivashko, Taishun Manjo, Maximilian Kauth +17
We investigate lattice dynamics in LaCoO using inelastic neutron and x-ray scattering over $T = 2\mbox{-}650\,\mathrm{K}$, spanning the spin-state crossover at $T_{1} \approx 1…
Observation of correlated plasmons in low-valence nickelates
Y. Shen, W. He, J. Sears +13
The discovery of nickelate superconductors has opened a new arena for studying the behavior of correlated electron liquids that give rise to unconventional superconductivity. While…
Signature of checkerboard fluctuations in the phonon spectra of a possible polaronic metal La1.2Sr1.8Mn2O7
F. Weber, N. Aliouane, H. Zheng +3
Charge carriers in low-doped semiconductors may distort the atomic lattice and trap themselves forming so-called small polarons. High carrier concentrations can lead to short range…
Coexistence of Weak Ferromagnetism and Ferroelectricity in the High Pressure LiNbO3-type Phase of FeTiO3
T. Varga, A. Kumar, E. Vlahos +11
We report the magnetic and electrical characteristics of a polycrystalline specimen of FeTiO3 synthesized at high pressure that is isostructural with acentric LiNbO3 (LBO). Piezore…
Full Bulk Spin Polarization and Intrinsic Tunnel Barriers at the Surface of Layered Manganites
J. W. Freeland, K. E. Gray, L. Ozyuzer +5
Transmission of information using the spin of the electron as well as its charge requires a high degree of spin polarization at surfaces. At surfaces however this degree of polariz…
Intrinsic chemical and structural inhomogeneity in lightly doped La(1-x)Sr(x)MnO(3)
Tomohiro Shibata, Bruce Bunker, John Mitchell +1
X-ray absorption fine structure measurements of the Sr and La K edges of the solid solution La(1-x)Sr(x)MnO(3) reveal a consistent deviation from a random distribution of Sr at the…
Interplay of spin and orbital ordering in the layered colossal magnetoresistance manganite La2-2xSr1+2xMn2O7 (0.5<=x<=1.0)
C. D. Ling, J. E. Millburn, J. F. Mitchell +2
The crystallographic and magnetic phase diagram of the n=2 layered manganite La2-2xSr1+2xMn2O7 in the region x=>0.5 has been studied using temperature dependent neutron powder diff…
Direct Imaging of the First Order Spin Flop Transition in the Layered Manganite La1.4Sr1.6Mn2O7
U. Welp, A. Berger, D. J. Miller +3
Magnetic field induced transitions in the antiferromagnetic layered manganite La1.4Sr1.6Mn2O7 were studied using magnetization measurements and a high-resolution magneto-optical im…
Lattice Displacements Above Tc in the Layered Manganite La1.2Sr1.8Mn2O7
D. N. Argyriou, H. N. Bordallo, J. F. Mitchell +2
Neutron diffraction data presented in this paper demonstrates the relevance of lattice displacement above TC, in our understanding of the evolution of the crystal structure with te…
Neutron scattering investigation of magnetic bilayer correlations in
R. Osborn, S. Rosenkranz, D. N. Argyriou +6
Neutron scattering investigations of the paramagnetic correlations in the layered manganite LaSrMnO, which exhibits colossal magnetoresistance above the…
