The understanding of relaxor ferroelectrics is hindered by the complexity of nanoscale perturbations of their structure. Here, a data set of independent techniques treated on common footing provides a multiscale description of atomic order which reco

Extended X-ray absorption fine structure (EXAFS) has evolved into an unprecedented local-structure technique that is routinely used to study materials’ problems in the biological, chemical, and physical sciences. Like many other experimental techni

Partial densities of states from x-ray absorption and Auger electron spectroscopy: Use of core-hole memory
Autor: Eric L. Shirley, C. Weiland, J. C. Woicik
Publikováno v: Phys Rev B
Ag [Formula: see text] edge x-ray absorption and [Formula: see text] Auger electron spectra have been measured and simulated for a variety of x-ray electric-field polarization and Auger electron emission directions. The theory relies on density-funct

Charge-transfer satellites and chemical bonding in photoemission and x-ray absorption of SrTiO
Autor: J C, Woicik, C, Weiland, C, Jaye, D A, Fischer, A K, Rumaiz, E L, Shirley, J J, Kas, J J, Rehr
Publikováno v: Phys Rev B
First-principles, real-time-cumulant, and Bethe-Salpeter-equation calculations fully capture the detailed satellite structure that occurs in response to the sudden creation of the core hole in both photoemission and x-ray absorption spectra of the tr

Multiferroic behavior in EuTiO3 films constrained by symmetry
Autor: Peter S. Normile, Philip Ryan, Paul Thompson, George E. Sterbinsky, D. G. Schlom, Simon Brown, Leyi Zhu, Jonathan Lang, J. S. Jiang, Turan Birol, J. W. Kim, June Hyuk Lee, J. C. Woicik, Yongseong Choi
Publikováno v: Physical Review B. 101
We have elucidated the spin, lattice, charge, and orbital coupling mechanism underlying the multiferroic character in tensile-strained $\mathrm{EuTi}{\mathrm{O}}_{3}$ films. Symmetry determined by oxygen octahedral tilting shapes the hybridization be

Journal de Physique IV Proceedings, EDP Sciences, 1997, 7 (C2), pp.C2-745-C2-747. ⟨10.1051/jp4:1997224⟩
The separate complex resonant scattering amplitudes for the two inequivalent Cu sites in YBa 2 CU 3 O 7-δ have been determined using diffraction anomalous fine structure (DAFS). The combined amplitudes Δf(Q,E) for eight specular (00l) reflections w
