Resonant soft x-ray scattering from DyMnO₃ — •Enrico Schierle, Victor Soltwisch, Detlef Schmitz, Ralf Feyerherm, Dimitri Argyriou, and Eugen Weschke — Hahn-Meitner-Institut, Berlin, Germany

The multiferroic compound DyMnO₃ was studied by resonant x-ray scattering at the Dy-M₅ and Mn-L₂ resonances in the temperature range between 5 K and 50 K. The element-selective resonant method permits to study ordering of the Dy-4f and Mn-3d moments seperately, revealing noticeable differences in the character of the ordered moments in the sinusoidal and the helical ferroelectric phase. From the energy dependence of the scattering cross section across the resonances details about ordering of magnetic moments and orbital wave functions can be inferred.
