MI-ThP-1 Synthesis and Size Dependent Magnetic Properties of Iron Oxide Nanoparticles Jeremy Winsett, Aric Moilanen, Suman Neupane (Middle Tennessee State University) Fe₂O₃, and Fe₃O₄ nanoparticles were synthesized by means of a simple hydrothermal procedure. The experimental parameters were varied to produce nanoparticles of different sizes and morphologies. Variation in growth temperature, duration, precursor concentration, and surfactants will influence the geometry and hence the magnetic properties of nanoparticles. Scanning electron microscopy, transmission emission microscopy and X-ray diffraction were used to characterize as-synthesized magnetic nanoparticles. Saturation magnetization and hysteresis measurement were determined using a vibrating sample magnetometer. Nanoparticles exhibiting size-dependent magnetic properties can find applications in targeted drug delivery, magnetic separation, contrast enhancement in magnetic imaging and others.
