Magnetic Property Study on Multi-Metal Compounds [M_A(en)_x]_y[Fe(CN)₆]_z·nH₂O(M_A=Co²⁺,Gu²⁺)

Abstract:

The cyano-bridged complexes [MA(en)x]y[Fe(CN)6]z·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 CN = 2117.27 cm-1 illustrates that there exists the bridged cyanide on the compound; the Curie temperature Ө is -8.23117 K, indicating the magnetic interaction between the metal ions in the compound is very weak.In the multi-metal compound CuII3[FeIII(CN)6]2·3NH3·6H2O, 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 Tc. The observed magnetic properties are explained with a ferromagnetic-spin-glass phase model.
