Resonant soft x-ray scattering from stepped surfaces of SrTiO3
J. Schlappa, C. Schüßler-Langeheine, C. F. Chang +9
We studied the resonant diffraction signal from stepped surfaces of SrTiO3 at the Ti 2p -> 3d (L2,3) resonance in comparison with x-ray absorption (XAS) and specular reflectivity d…
Direct observation of t2g orbital ordering in magnetite
J. Schlappa, C. Schuessler-Langeheine, C. F. Chang +8
Using soft-x-ray diffraction at the site-specific resonances in the Fe L23 edge, we find clear evidence for orbital and charge ordering in magnetite below the Verwey transition. Th…
Spectroscopy of stripe order in La1.8Sr0.2NiO4 using resonant soft x-ray diffraction
C. Schuessler-Langeheine, J. Schlappa, A. Tanaka +13
Strong resonant enhancements of the charge-order and spin-order superstructure-diffraction intensities in La1.8Sr0.2NiO4 are observed when x-ray energies in the vicinity of the Ni…
Metal-insulator Crossover Behavior at the Surface of NiS_2
D. D. Sarma, S. R. Krishnakumar, E. Weschke +8
We have performed a detailed high-resolution electron spectroscopic investigation of NiS and related Se-substituted compounds NiSSe, which are known to be gapped in…
The distribution of the doped holes in La2-xSrxCu1-yRuyO4-(delta)
Z. Hu, M. Knupfer, M. S. Golden +4
We present a systematic study of the perovskite-related system La2-xSrxCu1-yRuyO4 using Cu-L2,3, Ru-L2,3, and O-K x-ray absorption spectroscopy (XAS). This system can be regarded a…
The electronic structure of the doped one-dimensional transition metal oxide Y1-xCaxBaNiO5 studied using x-ray absorption
Z. Hu, M. Knupfer, M. Kielwein +6
A strong anisotropic distribution of the holes in Ni 3d and O 2p orbitals is observed in the polarization dependent O1s and Ni2p3/2 x-ray absorption spectroscopy of the linear-chai…
Localisation of doped holes in edge-shared CuO_2 chain cuprates: consequences for dynamic spectral weight transfer
Z. Hu, S. -L. Drechsler, J. Malek +9
We present a joint experimental and theoretical study of the electronic structure of the cuprate chain systems A_(1-x)CuO_2 (A=Ca,Sr,Ba), as measured using O-K and Cu-L_3 x-ray abs…
