The experimental study of photo-induced magnetization of hybrid molecular magnet containing cobalt(II) and tungsten(V) magnetic centers bridged by 4,4'-bpy and CN^- is presented. The observed increase in magnetization rate is attributed to the defects due to inter-valence transfer between Co^IIW^V↔ Co^IIIW^IV. The time evolution of magnetization is parameterized by the power law rather than exponential function.
