The synthesis of Fe 3 O 4 magnetic nanoparticles (MNPs) from iron ore as source of Fe3O4 has been done. Fe 3 O 4 MNPs were characterized by X-ray diffractometer (XRD) and Transmission Electron Microscope (TEM) for phase and size, Fourier Transform Infrared (FTIR) Spectrometer for bonding, and Vibrating Sample Magnetometer for magnetic properties. XRD pattern confirms the existence of a Fe 3 O 4 phase and size average 15 nm and suitable for magnetic nanoparticles. FTIR spectrum shows a band at 418-480 cm −1 and 603 cm −1 for the Fe-O bond vibration from Fe 3 O 4 . The coercivity, remanence, and magnetization saturation of the Fe3O4 MNPs studied in this investigation are 59.34 Oe, 30.43 emu/g, and 2.68 emu/g respectively and these observations indicate that the sample approaches towards superparamagnetic behaviour. This study agree with the result previously reported.
