Abstract:
We performed soft X-ray resonant scattering at the MnL (2,3)- and OK edges of YMn2O5. While the resonant intensity at the Mn L (2,3) 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 YMn2O5. We present details about how to obtain correct energy dependent lineshapes and discuss the origin of the resonant intensity at the O K edge.
