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…
Coupling of frustrated Ising spins to magnetic cycloid in multiferroic TbMnO3
O. Prokhnenko, R. Feyerherm, M. Mostovoy +5
We report on diffraction measurements on multiferroic TbMnO3 which demonstrate that the Tb- and Mn-magnetic orders are coupled below the ferroelectric transition TFE = 28 K. For T…
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…
Commensurate Dy magnetic ordering associated with incommensurate lattice distortion in orthorhombic DyMnO3
R. Feyerherm, E. Dudzik, N. Aliouane +1
Synchrotron x-ray diffraction and resonant magnetic scattering experiments on single crystal DyMnO3 have been carried out between 4 and 40 K. Below TN(Dy) = 5K, the Dy magnetic mom…
