Photoinduced perturbations of the magnetic superexchange in core@shell Prussian blue analogues

Below 70 K, Prussian blue analogue core@shell particles of K0.3Ni[Cr(CN)6]0.8·1.3H2O surrounding Rb0.4Co[Fe(CN)6]0.8·1.2H2O exhibit a photoinduced decrease in magnetization, which suggests a strain-induced decrease in the magnetization of the NiCr-PBA, as well as an accompanying perturbation of its superexchange, resulting from this photoinduced strain.
