Simple Synthesis of Micrometer Fe₃O₄ Particles with Controlled Magnetic Behaviors

Abstract:

Fe3O4 particles were prepared by the co-precipitating method in the presence of polyethylene glycol (PEG). They were characterized by the Transmittance electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscope, which indicate the formation of spherical Fe3O4 particles with a wide range of sizes (up to 200 nm in radius) and the polydispersity of particle size below 20%. Furthermore, the magnetic properties of Fe3O4 particles were measured using a vibrating sample magnetometer (VSM), indicating that the particles possess high saturation magnetization at room temperature. These results are attributed that the Fe3O4 particles were directly coated with PEG in a seeded growth Sto¨ber process.
