Writing and reading chiral domains in multiferroic DyMnO_3 using soft X-rays (2009)

Schierle, E., Soltwisch, V., Schmitz, D., Feyerherm, R., Maljuk, A., Yokaichiya, F., ...

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. This points to...

Ga substitution as an effective variation of Mn-Tb coupling in multiferroic TbMnO3 (2009)

Prokhnenko, O., Aliouane, N., Feyerherm, R., Dudzik, E., Wolter, A. U. B., Maljuk, A., ...

Ga for Mn substitution in multiferroic TbMnO$_{3}$ has been performed in order to study the influence of Mn-magnetic ordering on the Tb-magnetic sublattice. Complete characterization of...

CaFe2As2 under uniaxial pressure studied by neutron diffraction: Evidence for superconductivity in a stabilized tetragonal phase (2009)

Prokes, K., Kreyssig, A., Ouladdiaf, B., Pratt, D. K., Ni, N., Bud'ko, S. L., ...

CaFe2As2 single crystals under uniaxial pressure applied along the c axis exhibit the coexistence of several structural phases at low temperatures. We show that the room temperature tetragonal phase...

Low-energy Mott-Hubbard excitations in LaMnO_3 probed by optical ellipsometry (2009)

Kovaleva, N. N., Oles, Andrzej M., Balbashov, A. M., Maljuk, A., Argyriou, D. N., Khaliullin, G., ...

We present a comprehensive ellipsometric study of an untwinned, nearly stoichiometric LaMnO_3 crystal in the spectral range 1.2-6.0 eV at temperatures 20 K < T < 300 K. The complex dielectric...

Rare earth magnetism and ferroelectricity in RMnO3 (2009)

Feyerherm, R, Dudzik, E, Prokhnenko, O, Argyriou, D N

Magnetic rare earths R have been proven to have a significant effect on the multiferroic properties of the orthorhombic manganites RMnO3. A re-examination of previous results from synchrotron based...
