ResumoA series of uniform spinel ferrite MFe2O4 (M = Ni, Co, Mn, and Zn) nanoparticles (NPs) were successfully synthesized on a large scale by direct hydrothermal decomposition of the trinuclear heterometallic oxo-centered acetate cluster of [MFe2O(CH3CO2)6(H2O)3]nH2O 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 MFe2O4 NPs showed superparamagnetic properties at room temperature. The possible formation mechanism was also proposed.
