Static and fluctuating stripe order observed by resonant soft x-ray diffraction in La1.8Sr0.2NiO4
J. Schlappa, C. F. Chang, E. Schierle +11
We studied the stripe phase of La1.8Sr0.2NiO4 using neutron diffraction, resonant soft x-ray diffraction (RSXD) at the Ni L2,3 edges, and resonant x-ray diffraction (RXD) at the Ni…
Magnetic-field induced effects on the electric polarization in RMnO3 (R = Dy, Gd)
R. Feyerherm, E. Dudzik, A. U. B. Wolter +8
X-ray resonant magnetic scattering studies of rare earth magnetic ordering were performed on perovskite manganites RMnO3 (R = Dy, Gd) in an applied magnetic field. The data reveal…
Crystal-to-stripe reordering of sodium ions in NaxCoO2 (x>=0.75)
D. J. P. Morris, M. Roger, M. J. Gutmann +8
The sodium reordering in NaxCoO2 in the vicinity of room temperature is rationalized at high x in terms of phase transitions between square and striped phases. A striking hexagon-o…
Enhanced ferroelectric polarization by induced Dy spin-order in multiferroic DyMnO3
O. Prokhnenko, R. Feyerherm, E. Dudzik +4
Neutron powder diffraction and single crystal x-ray resonant magnetic scattering measurements suggest that Dy plays an active role in enhancing the ferroelectric polarization in mu…
