The lead ferrite (PbFe12O19) nanoparticles were prepared by a simple and short time microwave method. Lead nitrate, iron nitrate nine hydrate, surfactants, and ethylene glycol were used as precursor materials. The effect of surfactants on the morphology and particle size of the magnetic products was investigated. The prepared magnetic products were studied by X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy. Single phase hexagonal ferrite nanoparticles with average particle size of 50 nm were obtained in synthesize temperature of 850◦C. Alternating gradient force magnetometer approves magnetic property of the hexaferrite nanostructures. The values of both saturation magnetization and coercivity strongly depend on the particle sizes. The obtained hexagonal ferrite nanoparticles exhibit a hard magnetic feature with a suitable saturation magnetization.
