We tried to design the magnet exhibiting magnetic pole (N and S) inversion by photostimuli. The magnetization of Fe1.5IICrIII(CN)6·7.5H 2O was changed in a photon mode by visible light. A ferro-ferrimagnet (Fe0.40IIMno.60II) 1.5CrIII(CN)6·7.5H2O mixed by ferromagnetic (Fe-Cr system showing the change of magnetization by optical stimuli) site and ferrimagnetic (Mn-Cr system showing no optical response) site showed negative magnetization at the temperature lower than compensation temperature (Tcomp=19 K). In this mixed metal cyanide magnet we have succeeded in demonstrating a novel magnetic behavior "photoinduced magnetic pole inversion." Moreover, the magnetic pole inversion can be induced repeatedly by alternate optical and thermal stimulations.
