Magneto-electric multiferroics exemplified by TbMnO(3) possess both magnetic and ferroelectric long-range order. The magnetic order is mostly understood, whereas the nature of the ferroelectricity has remained more elusive. Competing models proposed to explain the ferroelectricity are associated respectively with charge transfer and ionic displacements.(More)
Magnetic resonant x-ray scattering experiments have been performed on a single crystal of EuFe 2 As 2 at the Eu L 3 absorption edge. The orientation of Eu magnetic moments was directly determined: in the antiferromagnetic ordered phase they lay parallel to the crystallographic a-axis. In addition, non-resonant magnetic x-ray measurements indicate that Fe(More)
