Preparation of Super Paramagnetic Iron Oxide Nanoparticles and Investigation their Magnetic Properties

Journal Name:

Publication Year:

Abstract (2. Language): 
Super paramagnetic Iron Oxide nanoparticles were prepared by co-precipitation method using NaOH as precipitation agent. Magnetic properties of nanoparticles were measured by a VSM. The crystallite size of particles was calculated by Sherrer formula and magnetic data and compared with the size of nanoparticles which obtained by TEM. The sizes of produced nanoparticles were about 11 nanometer and their saturation magnetizations were 69 emu/gr.
