摘要

One of the Prussian blue analogs, molecular magnet CuⅡ3[FeⅢ (CN)6]2.11.6H2O, was investigated by Mossbauer spectroscopy. It was found that transition temperature was around TC = 18.5 K from paramagnetic phase to ferromagnetic phase. Theβ value of the critical exponent is around 0.338 at magnetic ordering temperature.Therefore, the ferromagnetic coupling interaction of Cu-Fe cyanide could be clearly explained by spin wave theory.
