Core/shell particles comprised of the ferromagnet KjNik[Cr(CN)6]l�nH2O over a core of the photoinducible ferrimagnet RbjCok[Fe(CN)6]l�nH2O have been prepared. After irradiation with visible light, the heterostructures undergo a persistent photoinduced decrease in magnetization. The results suggest that structural changes in the photoactive core distort the photoinactive shell leading to a change in its magnetization. The synthesis of particles with various shell thickness provides new insights on the pressure induced mechanisms giving rise to the decrease in magnetization.
