Mossbauer Evidence for Ferromagnetic Ordering in Copper-Iron Cyanometallates
，-0001，（）：
A novel member of the Prussian blue family, cu3Ⅱ [FeⅢ (CN) 6] 2. 3NH3·6H2O, was synthesized, in which NH3 ligands are in stochastic distribution. We present x-ray diffraction data, zero-field-cooled magnetization and field-cooled magnetization curves, Mössbauer spectra with/without an xternal Field of 5 T and a structural model. This Prussian blue analogue displays considerable magnetic hardness below the magnetic transition temperature Tc, which is about 19.8K. The coercive field determined from the magnetization hysteresis loop at 5 K was 2.76 kOe. The copper-iron cyanometallates have potentlal applications in the design of novel magnetic systems.
