The Effects of Cu and Zn Dopants on Phase Constituents, Magnetic Properties and Microstructure of Nickel Ferrite
In this research nanoparticles of Ni0.55Zn0.35Cu0.1Fe2O4 were synthesized by sol–gel auto-combustion method. Changes in phase constituents, microstructure and magnetic properties as a result of Zn and Cu additions were evaluated by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), and Vibration Sample Magnetometer (VSM) techniques. XRD results show that the doped sam...
متن کاملEffects of annealing on phase evolution, microstructure and magnetic properties of mechanically synthesized nickel-ferrite
The influence of milling and subsequent annealing on nickel-ferrite phase formation was investigated by X-ray diffraction (XRD). Microstructure and magnetic properties of NiFe2O4 were determined by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and vibration sample magnetometry (VSM). Single phase nanosized nickel-ferrite was obtained by 30 h mechani...
متن کاملElectromagnetic and microwave-absorbing properties of magnetic nickel ferrite nanocrystals.
The electromagnetic and microwave absorbing properties of nickel ferrite nanocrystals were investigated for the first time. There were two frequencies corresponding to the maximum reflection loss in a wide thickness range from 3.0 to 5.0 mm, which may be bought by the nanosize effect and the good crystallization of the nanocrystals.
متن کاملMagnetic Properties of Nano Crystalline Nickel, Samariumdoped Zinc Ferrite
Nano-particles of polycrystalline Zn Fe2 O4 are prepared using sol-gel method with Ni, and Sm. They are obtained as dried gel after the successful chemical reaction of their respective metal nitrate solutions in the midst of citric acid as catalyst. Synthesis of materials is confirmed using XRD from the report of single phase polycrystalline ferrite material. The magnetic properties of Zn-ferri...
متن کاملHeat treatment effects on microstructure and magnetic properties of Mn–Zn ferrite powders
Mn–Zn ferrite powders (Mn0.5Zn0.5Fe2O4) were prepared by the nitrate–citrate auto-combustion method and subsequently annealed in air or argon. The effects of heat treatment temperature on crystalline phases formation, microstructure and magnetic properties of Mn–Zn ferrite were investigated by X-ray diffraction, thermogravimetric and differential thermal analysis, scanning electron microscopy a...
