Magnetic Property Study on multi-metal compounds MA(en)xyFe(CN)6z·nH2O(MA=Co2+,Gu2*)
The cyano-bridged complexes MA(en)xyFe(CN)6z·nH2O(MA=Co2+,Gu2+) have been synthesized.In the multi-metal compound Co(en)3 Fe(CN)6·6.1H2O was prepared.Infrared spectra with stretching vibration vcN =2117.27 cm-1 illustrates that there exists the bridged cyanide on the compound; the Curie temperature θ is-8.23117 K,indicating the magnetic interaction between the metal ions in the compound is very weak.In the multi-metal compound CuⅡ3FeⅢ(CN)62·3NH3·6H2O,we shows firstly the coexistence of ferromagnetic order and spin-glass order.The irreversibility in the MFc/MzFc and the relaxation of MZFC suggest that the magnetic system can be visualized as containing a ferromagnetic cluster of spin below Tc,mixed with small spin-glass clusters formed below temperature Tg less than To.The observed magnetic properties are explained with a ferromagnetic-spin-glass phase model.
