Raman scattering study and lattice-dynamics calculations in YTiO3: Precursor of the magnetic phase transition in the phonon anomalies
N. N. Kovaleva, O. E. Kusmartseva, A. Maljuk
The origin of the low-temperature ferromagnetic instability in YTiO3 driven by the interplay between lattice, orbital, spin, and charge degrees of freedom is on the background of l…
Reduced crystal symmetry as origin of the ferroelectric polarization within the incommensurate magnetic phase of TbMn2O5
N. Narayanan, P. J. Graham, P. Rovillain +9
The precise crystal symmetry and hence the emergence of the electric polarization still remains an open question in the multiferroic materials MnO ( = rare-earth, Bi,…
The role of the nominal iron content in the structural, compositional and physical properties of BaFeS
M. L. Amigó, Q. Stahl, A. Maljuk +6
BaFeS is a quasi-one-dimensional antiferromagnetic insulator that becomes superconducting under hydrostatic pressure. The magnetic ordering temperature, , as well as t…
Acoustic signatures of the phases and phase transitions in YbTiO
Subhro Bhattacharjee, S. Erfanifam, E. L. Green +11
We report on measurements of the sound velocity and attenuation in a single crystal of the candidate quantum- spin-ice material YbTiO as a function of temperature and m…
Disparity of superconducting and pseudogap scales in low-Tc Bi-2201 cuprates
Th. Jacobs, S. O. Katterwe, H. Motzkau +7
We experimentally study transport and intrinsic tunneling characteristics of a single-layer cuprate Bi(2+x)Sr(2-y)CuO(6+delta) with a low superconducting critical temperature Tc <…
Writing and reading chiral domains in multiferroic DyMnO_3 using soft X-rays
E. Schierle, V. Soltwisch, D. Schmitz +5
Sizeable b and c components of the 4f moments and pronounced circular dichroism are observed in the ferroelectric phase of DyMnO_3 by soft X-ray diffraction at the Dy-M_5 resonance…
Magnetic field induced flop of cycloidal spin order in multiferroic TbMnO3: The magnetic structure of the P||a phase
N. Aliouane, K. Schmalzl, D. Senff +4
Using in-field single crystal neutron diffraction we have determined the magnetic structure of TbMnO3 in the high field P||a phase. We unambiguously establish that the ferroelectri…
