摘要：

Static and dynamic magnetic properties and photoinduced magnetism of a Co-Fe Prussian blue analog, K1-2xCo1+x[Fe(CN)(6)]. gammaH(2)O (x approximate to 0.2,y approximate to 4.9), are studied in detail. The magnetic behavior of the material is indicative of a cluster glass state. Our model of 'spin doping' of cluster glass is consistent with the observed photoinduced magnetic effects, including the previously unaccounted for increase in coercivity.
