Unidirectional Diagonal Order and 3D Stacking of Charge Stripes in Orthorhombic Pr1.67Sr0.33NiO4 and Nd1.67Sr0.33NiO4
M. Huecker, M. v. Zimmermann, R. Klingeler +9
The interplay between crystal symmetry and charge stripe order in Pr1.67Sr0.33NiO4 and Nd1.67Sr0.33NiO4 has been studied by means of single crystal x-ray diffraction. In contrast t…
Octahedral tilts and electronic correlations in La_7/8Sr_1/8MnO_3
J. Geck, P. Wochner, S. Kiele +3
We present a resonant x-ray scattering study of the octahedral tilt order between 50K and 310K in La_7/8Sr_1/8MnO_3. At the La L_II-edge the resonant (300) reflection probes cooper…
Orbital polaron lattice formation in lightly doped La1-xSrxMnO3
J. Geck, P. Wochner, S. Kiele +4
By resonant x-ray scattering at the Mn K-edge on La7/8Sr1/8MnO3, we show that an orbital polaron lattice (OPL) develops at the metal-insulator transition of this compound. This orb…
Structural modulations in and their relation to charge ordering
M. v. Zimmermann, J. Geck, S. Kiele +2
Structural properties of the spin chain and ladder compound SrCuO have been studied using diffraction with hard x-rays. Strong incommensurate modulation reflec…
