NiO Nanoparticles: Synthesis and Characterization
In the current paper,Nanostructured Nickel oxide (NiO) were synthesized by co-precipitation method using Nickel(II) Chloride Hexahydrate (NiCl2.6H2O) and sodium hydroxide (NaOH) as starting material. Structural, optical and magnetic properties of nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Atomic force microscope (AFM), UV–Vis absorption; Fo...
متن کاملSuperparamagnetic Behavior of the Magnetic Hysteresis Loop in the Fe2O3@Pt Core-Shell Nanoparticles
Studies of the magnetization of Fe2O3@Pt nanoparticles at room temperature showed that there is superparamagnetic contribution with high saturation magnetization about 12.35(emu/g), and soft ferromagnetic contribution with narrow coercive field about 58(Oe). In this paper we fitted the hystersis loop of sample with Brillouin function that demonstrating existence of superparamagnetic phase. Tota...
متن کاملSynthesis and Characterization of Nickel Zinc Ferrite Nanoparticles
In this research nickel zinc ferrite nanoparticles with composition of Ni1-xZnxFe2O4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °C for 5 hours. The structure of nanoparticles was studied using X-ray diffraction pattern. The lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticl...
متن کاملSynthesis and Characterization of Carbon Nanotubes Decorated with Magnesium Ferrite (MgFe2O4) Nanoparticles by Citrate-Gel Method
In the present work, magnetic nanocomposites of the multi-walled carbon nanotubes (MWCNTs) decorated with magnesium ferrite (MgFe2O4) nanoparticles were synthesized successfully by citrate-gel method. The shape, structure, size, and properties of the as-synthesized sample were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction pattern (XRD), transmission electron...
متن کاملRotation of Magnetization Derived from Brownian Relaxation in Magnetic Fluids of Different Viscosity Evaluated by Dynamic Hysteresis Measurements over a Wide Frequency Range
The dependence of magnetic relaxation on particle parameters, such as the size and anisotropy, has been conventionally discussed. In addition, the influences of external conditions, such as the intensity and frequency of the applied field, the surrounding viscosity, and the temperature on the magnetic relaxation have been researched. According to one of the basic theories regarding magnetic rel...
