Abstract: Abstract: We performed soft X-ray resonant scattering at the MnL <subscript>2,3</subscript>- and OK edges of YMn<subscript>2</subscript>O<subscript>5</subscript>. While the resonant intensity at the Mn L <subscript>2,3</subscript> edges reflects the magnetic order parameter, the resonant scattering at the O K edge is found to be directly related to the macroscopic ferroelectric polarization. The latter observation reveals the important role of the spin-dependent Mn-O hybridization for the multiferroicity of YMn<subscript>2</subscript>O<subscript>5</subscript>. We present details about how to obtain correct energy dependent lineshapes and discuss the origin of the resonant intensity at the O K edge.
