Resonant Soft X-ray Scattering (RSXS) Studies on Multiferroic YMn2O5 with six circle diffractometer and CCD-camera — •Sven Partzsch¹, Stuart Wilkins², John Hill², Enrico Schierle³, Eugen Weschke³, Dmitri Souptel¹, Bernd Büchner¹, and Jochen Geck¹ — ¹IFW Dresden — ²BNL Upton — ³Helmholz-Zentrum Berlin

RMn₂O₅ (R = Y, rare earth, Bi) are multiferroics there RSXS at the magnetic modulation vector (1/2, 0, 1/4) provide additional information to neutrons. By tuning the energy to the Mn L- and O K-edges, respectively, the experiment becomes element selective. To see which scattering is proportional to the electric polarization the integrated intensity is important. For this we performed experiments at X1A2 (Tardis), NSLS, BNL, Upton, New York, USA. Four moving motors in six circle geometry and a CCD-camera provided the integrated intensity and all widths in three principal directions with one scan (set of images). Thus this technique is practical to study strongly correlated electron systems.
