Magnetic 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 کاملChemical Synthesis of Nano-Crystalline Nickel-Zinc Ferrite as a Magnetic Pigment
The nano-crystalline nickel-zinc ferrite was prepared via chemical synthesis. Zinc nitrate, nickel nitrate, iron nitrate hydrate, citric acid and ethylene glycol were used as precursor materials. Crystallization behavior of the precursor was studied by X-ray diffraction (XRD). Nanoparticle phases can change amorphous to spinel ferrite depending on the calcination temperature and crystallite siz...
متن کاملPreparation and magnetic properties of nano size nickel ferrite particles using hydrothermal method
BACKGROUND Nickel ferrite, a kind of soft magnetic materials is one of the most attracting class of materials due to its interesting and important properties and has many technical applications, such as in catalysis, sensors and so on. In this paper the synthesis of NiFe2O4 nanoparticles by the hydrothermal method is reported and the inhibition of surfactant (Glycerol or Sodium dodecyl sulfate)...
متن کاملMagnetic and structural properties of nickel zinc ferrite nanoparticles synthesized at room temperature
Nickel zinc ferrite nanoparticles (Ni0.20Zn0.44Fe2.36O4) have been produced at room temperature, without calcination, using a reverse micelle process. Particle size is approximately 7 nm as determined by x-ray powder diffraction and transmission electron microscopy. Saturation magnetization values are lower than anticipated, but are explained by elemental analysis, particle size, and cation occ...
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.
