The structural and magnetic properties of the polyethylene glycol (PEG) coated nickel spinel ferrite (NiFe2O4) nanoparticles have been reported in the present study. NiFe2O4 nanoparticles were prepared by solution plasma method using KOH + Na2Co3 as electrolyte. The prepared powder of nickel ferrite nanoparticles was annealed at 800 ˚C for two h and used for further study. The X-ray analysis confirmed the formation of a cubic spinel single-phase structure. The crystallite size, lattice parameter, and X-ray density of the PEG-coated NiFe2O4 nanoparticles were calculated using XRD data. TEM and FTIR studies revealed the presence of PEG on nickel ferrite nanoparticles and reduced agglomeration in the NiFe2O4 nanoparticles. The pulse-field hysteresis loop tracer technique studied the magnetic properties at room temperature. The magnetic parameters such as saturation magnetization, remanence magnetization, and coercivity have been obtained. These magnetic parameters were get decreased by PEG coating.
