The static, dynamic and attenuation properties of Co2Z barium ferrites and Co2Z composites have been studied. The results showed that both static and dynamic magnetic properties are significantly different for large particles and nanoparticles. As compared to large particles, Co2Z nanoparticles have a small saturation magnetization Ms , large coercivity Hc , small permeability μ0 and μ ′′ max, ...

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 electro...

In this work, the investigation of wave absorption, phase formation, crystal structure and magnetic properties of SrFe12O19 hexa-ferrites nanoparticles that synthesized by co-precipitation using a microwave heating system and polyaniline-SrFe12O19 was carried out by using a combination of vector network analyser (VNA), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier tra...

Nano-sized crystallites of iron oxide were synthesized by cost effective co-precipitation method. X-ray diffraction pattern indicated that the magnetic nanoparticles were pure Fe3O4 with a spinel structure. The nanoparticles were characterized by X-ray diffraction (XRD), Fourier-Transform Infrared (FT-IR) spectra, Transmission electron microscope (TEM) and magnetization measurement of the nanop...

In this work, the effects of co-precipitation temperature and post calcination on the magnetic properties and photocatalytic activities of ZnFe2O4 nanoparticles were investigated. The structure, magnetic and optical properties of zinc ferrite nanoparticles were characterized by X-ray diffraction (XRD), vibrating sample magnetometry and UV–Vis spectrophotometry techniques.  The XRD re...

Due to finite size effects, such as the high surface-to-volume ratio and different crystal structures, magnetic nanoparticles are found to exhibit interesting and considerably different magnetic properties than those found in their corresponding bulk materials. These nanoparticles can be synthesized in several ways (e.g., chemical and physical) with controllable sizes enabling their comparison ...

Magnetic CoFe2O4 nanoparticles were synthesized via a simple chemical reaction using precipitation method. The obtained materials consist of ferrite particles with average diameter of 25 nm. The effect of different surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. Scanning electron microscopy was used to study the structure and particle size o...
