Double perovskite Bi2FeMnO6 is a potentialcandidate for the single-phase multiferroic system. In this work, we study themagnetic, electronic, and optical properties in BFMO by performing the density functional theorycalculations and experimental measurements of magnetic moment. We alsodemonstrate the strain dependence of magnetization. More importantly, our calculations ofelectronic and optical properties reveal that the onsite local correlation on Mn andFe sites is critical to the gap opening in BFMO, which is a prerequisite conditionfor the ferroelectric ordering. Finally, we calculate the x-ray magnetic circulardichroism spectra of Fe and Mn ions (L2 and L3 edges) inBFMO
