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…

Charge order, dynamics, and magneto-structural transition in multiferroic LuFeO

X. S. Xu, M. Angst, T. V. Brinzari +8

We investigated the series of temperature and field-driven transitions in LuFeO by optical and Mössbauer spectroscopies, magnetization, and x-ray scattering in order to und…

Charge order in LuFe2O4: antiferroelectric ground state and coupling to magnetism

M. Angst, R. P. Hermann, A. D. Christianson +10

X-ray scattering by multiferroic LuFe2O4 is reported. Below 320 K, superstructure reflections indicate an incommensurate charge order with propagation close to (1/3,1/3,3/2). The c…

Phase transitions in LaFeAsO: structural, magnetic, elastic, and transport properties, heat capacity and Mossbauer spectra

Michael A. McGuire, Andrew D. Christianson, Athena S. Sefat +13

We present results from a detailed experimental investigation of LaFeAsO, the parent material in the series of "FeAs" based oxypnictide superconductors. Upon cooling this material…

Evidence for the Spin Density Wave in LaFeAsO

M. A. McGuire, A. D. Christianson, A. S. Sefat +5

This paper has been withdrawn by the authors due to errors in the X-ray diffraction data. Other measured data are not affected; however, the errors significantly change the interpr…
