Abstract

The aim of this study was to investigate nickel ferrite (NiFe2O4) plate nanoparticles synthesized by the co-precipitation method. The effects of parameters such as solution pH and Fe3+/Ni2+ mole ratio of nickel ferrite nanoparticles were analyzed. The nanoparticles synthesized by the co-precipitation method were calcined at 650°C. The samples were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray analysis (EDAX), and Fourier-transform infrared spectroscopy (FTIR). The remanent magnetization, saturated magnetism, and coercivity properties of the samples were measured with a vibrating sample magnetometer (VSM). In a synthesis process with Fe3+/Ni2+ = 1 mole ratio, a Ni1.43Fe1.7O4 compound was formed where NiFe2O4 was expected to form. NiFe2O4 plate nanoparticles with 108-nm particle size were successfully synthesized using the Fe3+/Ni2+ = 2 mole ratio.
