摘要：

A series of uniform spinel ferrite MFe(2)O(4) (M = Ni, Co, Mn, and Zn) nanoparticles (NPs) were successfully synthesized on a large scale by direct hydrothermal decomposition of the trinuclear heterornetallic oxocentered acetate cluster of [MFe(2)O(CH(3)CO(2))(6)(H(2)O)(3)]center dot nH(2)O in solution. The crystal structure, composition and size of the synthesized NPs were characterized by X-ray diffraction (XRD), inductively coupled plasma atomic emission spectrometer (ICP-AES), transmission electron microscope (TEM) and high-resolution (HRTEM). Magnetic investigation revealed that all the synthesized MFe(2)O(4) NPs showed superparamagnetic properties at room temperature. The possible formation mechanism was also proposed.
