Study on Magnetic Properties of Iron Oxide Nanoparticles Prepared by Thermal Decomposition Method

In this study, iron oxide nanoparticles were synthesized by thermal decomposition method using Fe(acac)(3) and 1-hexadecanol at 330 degrees C. TG-DSC is one of the most important characterization techniques to study the Fe3O4 nanoparticles generation and growth from reduced mass and endothermal reaction. Analysis of TEM and XRD results yield the average sizes of synthesized spherical magnetite nanoparticles with sizes of 10nm. We could determine the saturation magnetization and coercivity value using the VSM. ZFC and FC curves measured at 100 Oe with the T-B (blocking temperature) was explained to superparamagnetic transition.
