Metal dilution effects on the switching properties of CoFe Prussian blue analogues

Recent years have seen the discovery of unusual and fascinating electronic properties in Prussian blue analogues. Thus, some CoFe Prussian blue analogues exhibit a photomagnetic effect. Here, we present the first study of metal dilution effect on the switching properties in two different CoFe Prussian blue analogues. This investigation shows that metal dilution strongly depends on the stoichiometry of the compounds and the nature of the diluting agents. The switching properties can either be totally killed for low dilution rate or be persist at a CoFe pair scale.
