microwave synthesis of different morphologies of lead ferrite nanostructures and investigation of magnetic properties

the lead ferrite (pbfe12o19) nanoparticles were prepared by a simple and short time microwave method. lead nitrate, iron nitrate 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 study by x-ray diffraction (xrd), scanning electron microscopy (sem), and fourier transform infrared (ft-ir) spectroscopy. single hexagonal ferrite phase nanoparticles with average particle size of 50nm could be obtained in 850◦c. alternating gradient force magnetometer approves magnetic property of the hexaferrite nanostructures. both the saturation magnetization and coercivity are strongly dependent on the particle sizes. the obtained hexagonal ferrite nanoparticles exhibit a hard magnetic feature with a suitable saturation magnetization.
