Mössbauer Investigation of the Ferromagnetic Coupling in Copper-Iron Polycyanides
-
Abstract
One of the Prussian blue analogs, molecular magnet CuII3FeIII(CN)62.11.6H2O, was investigated by Mössbauer spectroscopy. It was found that transition temperature was around TC = 18.5 K from paramagnetic phase to ferromagnetic phase. The β 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.
