Phonon softening near structural transition in BaFe2As2 observed by inelastic x-ray scattering
Jennifer L. Niedziela, D. Parshall, K. A. Lokshin +3
In this work we present the results of an inelastic x-ray scattering experiment detailing the behavior of the transverse acoustic [110] phonon in BaFe2As2 as a function of temperat…
Bulk magnetic order in a two dimensional Ni1+/Ni2+ (d9/d8) nickelate, isoelectronic with superconducting cuprates
Viktor V. Poltavets, Konstantin A. Lokshin, Takeshi Egami +10
Bulk magnetic order in two dimensional La4Ni3O8 nickelate with Ni1+/Ni2+ (d9/d8), isoelectronic with superconducting cuprates is demonstrated experimentally and theoretically. Magn…
Phonons as a probe of the magnetic state in doped and undoped BaFe2As2
D. Reznik, K. Lokshin, D. C. Mitchell +17
We measured phonon frequencies and linewidths in doped and undoped BaFe2As2 single crystals by inelastic x-ray scattering and compared our results with density functional theory (D…
Spin Excitations in BaFe1.84Co0.16As2 Superconductor Observed by Inelastic Neutron Scattering
D. Parshall, K. A. Lokshin, Jennifer Niedziela +11
Superconductivity appears to compete against the spin-density-wave in Fe pnictides. However, optimally cobalt doped samples show a quasi-two-dimensional spin excitation centered at…
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…
C-axis Phonons in Fe-As Based Superconductors Investigated by Inelastic X-ray Scattering
D. Reznik, K. Lokshin, D. C. Mitchell +16
In Fe-As based superconductors magnetism and superconductivity show strong sensitivity to the lattice, suggesting a possibility of unconventional electron-phonon coupling. We inves…
