摘要
Nanoparticles of Prussian blue analogues Ni-3[Fe(CN)(6)]center dot 8.28H(2)O have been successfully synthesized by co-precipitation method. The nanoparticles were characterized by elemental analysis, X-ray diffraction, Fourier transform infrared spectrometry and transmission electron microscopy. Magnetic measurement was carried by superconducting quantum interference device magnetometer and the result showed the the transition temperature T-c = 22.8 K. The interaction between Ni(II) and Fe(II) was identified to be a kind of ferromagnetic coupling and was clearly explained by molecular orbital theory. The Mossbauer spectra have been used to explain the origin of magnetism.
