A μSR study of the magnetism in Prussian Blue analogue photomagnets

In this work we present longitudinal field μSR results in the molecular magnetic Co-Fe Prussian Blue analogue Rb1-2xCo1+x[Fe(CN)6]·zH2O, with x≈0.17 which exhibits light induced magnetic ordering. We were unable to observe the effect of light with μSR, but in the reportedly paramagnetic unilluminated state, we find evidence for glassy magnetic freezing.
