Journal ArticleDOI
Magnetic structure of Fe/Gd multilayers determined by resonant x-ray magnetic scattering
Naoki Ishimatsu,Hiroo Hashizume,S. Hamada,Nobuyoshi Hosoito,C. S. Nelson,C. T. Venkataraman,George Srajer,Jonathan Lang +7 more
TL;DR: In this article, the magnetic structures of a multilayer multi-layer were determined by resonant x-ray magnetic scattering using circular polarized light of energies tuned close to the Gd L and the Fe K absorption edges.
Journal ArticleDOI
Correlated polarons in dissimilar perovskite manganites
Christie Nelson,M. v. Zimmermann,Young-June Kim,John Hill,Doon Gibbs,Valery Kiryukhin,T. Y. Koo,T. Y. Koo,Sang-Wook Cheong,Sang-Wook Cheong,Diego Casa,Bernhard Keimer,Y. Tomioka,Yoshinori Tokura,Thomas Gog,C. T. Venkataraman +15 more
TL;DR: In this paper, x-ray scattering studies of broad peaks located at (0.5 0 0)/(0 0.5 )-type wave vectors in the paramagnetic insulating phases of the electron-phonon coupling were performed.
Journal ArticleDOI
X-ray resonant magnetic scattering from structurally and magnetically rough interfaces in multilayered systems. II. Diffuse scattering
Dong Ryeol Lee,Sunil K. Sinha,Sunil K. Sinha,C. S. Nelson,Jonathan Lang,C. T. Venkataraman,George Srajer,Richard M. Osgood +7 more
TL;DR: In this paper, the theoretical formulation of x-ray resonant magnetic scattering from rough surfaces and interfaces is given for the diffuse (off-specular) scattering, and general expressions are derived in both the Born approximation (BA) and the distorted-wave Born approximation for both single and multiple interfaces.
Journal ArticleDOI
Doping dependence of charge-transfer excitations in La 2 − x Sr x CuO 4
TL;DR: In this paper, a resonant inelastic x-ray scattering (RIXS) study of the doping dependence of charge-transfer excitations in the Brillouin zone was performed.
Journal ArticleDOI
Charge-magnetic roughness correlations in an Fe/Gd multilayer
C. S. Nelson,C. S. Nelson,George Srajer,Jonathan Lang,C. T. Venkataraman,S. K. Sinha,Hiroo Hashizume,Naoki Ishimatsu,Nobuyoshi Hosoito +8 more
TL;DR: In this article, the intrinsic charge-magnetic roughness correlations of the Gd layers in an Fe/Gd multilayer were studied using diffuse, x-ray resonant magnetic scattering.
