Low-temperature ferroelectric phase and magnetoelectric coupling in the underdoped La_2CuO_(4+x)
Z. Viskadourakis, I. Radulov, A. P. Petrović +9
We report the discovery of a ferroelectric ground state below 4.5 K in highly underdoped La_2CuO_(4+x) accompanied by slow charge dynamics which develop below T~40 K. An anisotropi…
Solitonic lattice and Yukawa forces in the rare earth orthoferrite TbFeO3
Sergey Artyukhin, Maxim Mostovoy, Niels Paduraru Jensen +13
The control of domains in ferroic devices lies at the heart of their potential for technological applications. Multiferroic materials offer another level of complexity as domains c…
Transition from a phase-segregated state to single-phase incommensurate sodium ordering in Na_xCoO_2 with x \approx 0.53
R. Feyerherm, E. Dudzik, S. Valencia +5
Synchrotron X-ray diffraction investigations of two single crystals of Na_xCoO_2 from different batches with composition x = 0.525-0.530 reveal homogeneous incommensurate sodium or…
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…
Magnetic field induced transitions in multiferroic TbMnO3 probed by resonant and non-resonant X-ray diffraction
J. Strempfer, B. Bohnenbuck, I. Zegkinoglou +4
Multiferroic TbMnO3 is investigated using x-ray diffraction in high magnetic fields. Measurements on first and second harmonic structural reflections due to modulations induced by…
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…
