| Abstract: | Magnetic NiFe2O4 (NiFe) nanoparticles were synthesized via a facile chemical reaction between Ni(NO3)2 and Fe(NO3)3. Different percents of NiFe nanoparticles were then added to polystyrene (PS) matrix. Nanoparticles were characterized using X-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. The nanoparticles exhibit ferromagnetic behaviour at room temperature, with a saturation magnetization of 20.8 emu/g and a coercivity of 99.6 Oe. Preparation of NiFe2O4 -PS nanocomposite leads to decrease in the coercivity. |
