Neutron powder diffraction atomic pair distribution function analysis using the ARCS chopper spectrometer at the Spallation Neutron Source
E. S. Bozin, P. Juhas, W. Zhou +4
The frst neutron powder diffraction based atomic pair distribution functions (PDFs) are reported from the new wide angular-range chopper spectrometer ARCS at the Spallation Neutron…
Two-dimensional resonant magnetic excitation in BaFe1.84Co0.16As2
M. D. Lumsden, A. D. Christianson, D. Parshall +14
Inelastic neutron scattering measurements on single crystals of superconducting BaFe1.84Co0.16As2 reveal a magnetic excitation located at wavevectors (1/2 1/2 L) in tetragonal nota…
Phonon Density of States of LaFeAsO1-xFx
A. D. Christianson, M. D. Lumsden, O. Delaire +16
We have studied the phonon density of states (PDOS) in LaFeAsO1-xFx with inelastic neutron scattering methods. The PDOS of the parent compound(x=0) is very similar to the PDOS of s…
Destruction of Neel order and appearance of superconductivity in electron-doped cuprates by oxygen annealing process
Shiliang Li, Songxue Chi, Jun Zhao +4
We use thermodynamic and neutron scattering measurements to study the effect of oxygen annealing on the superconductivity and magnetism in PrLaCeCuO. Alth…
Singlet-triplet dispersion reveals additional frustration in the triangular dimer compound BaMnO
M. B. Stone, M. D. Lumsden, S. Chang +3
We present single crystal inelastic neutron scattering measurements of the S=1 dimerized quasi-two-dimensional antiferromagnet BaMnO. The singlet-triplet dispersion rev…
Dispersive magnetic excitations in the S=1 antiferromagnet BaMnO
M. B. Stone, M. D. Lumsden, Y. Qiu +3
We present powder inelastic neutron scattering measurements of the S=1 dimerized antiferromagnet BaMnO. The K magnetic spectrum exhibits a spin-gap of $Δ\approx…
