CoFe 2 O 4 magnetic nanoparticles (MNPs) were successfully co-precipitated by refluxing method and followed by high temperature calcination. Phase, morphology, oxidation state and magnetic property were characterized by a selected area electron diffraction (SAED) technique, a transmission electron microscope (TEM), a scanning electron microscope (SEM), an X-ray photoelectron spectrometer (XPS), a Fourier transform infrared (FTIR) spectrometer, a Raman spectrophotometer and a vibrating sample magnetometer (VSM). The CoFe 2 O 4 MNPs were also studied for magnetic resonance imaging (MRI). They were found to have very high r 2 relaxivity of 1,313 mM −1 · s −1 and were able to be used for MRI application with very good contrast.
