The photo-induced decrease in magnetization ΔM_{photo} was observed in Cd_{1-x}Mn_{x}Te (0.25 < x < 0.42) under unpolarized light illumination whose photon energy is smaller than the band gap of the sample. The photo-induced magnetization decreases with increasing Mn content through Mn^{2+}-Mn^{2+} antiferromagnetic interaction, which supports our idea for origin of it based on the flipping of Mn spins in the bound magnetic polarons accompanied by the spin-flip Raman scattering.
