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. © 2021, The Minerals, Metals & Materials Society.EnglishCoprecipitationEnergy dispersive X ray analysisFerriteFourier transform infrared spectroscopyIron compoundsNanomagneticsNanoparticlesNickelParticle sizeParticle size analysisScanning electron microscopySynthesis (chemical)X ray diffraction analysisCoprecipitation methodEffect of parametersFe 3+Mole ratioNickel ferriteNickel ferrite nanoparticlePropertyRemanent magnetizationSolution pHSynthesisedNickel compoundsArticle10.1007/s11837-021-04982-7
