Magnetic and Structural Investigations of Nanocrystalline Cobalt-Ferrite
Cobalt ferrite is an important magnetic material due to their large magneto-crystalline anisotropy, high cohercivity, moderate saturation magnetization and chemical stability.In this study, cobalt ferrites Nanoparticles have been synthesized by the co-precipitation method and a new microemulsion route. We examined the cation occupancy in the spinel structure based on the “Rietveld with energies...
متن کاملPhysical and magnetic properties of highly aluminum doped strontium ferrite nanoparticles prepared by auto-combustion route
Highly Al3þ ion doped nanocrystalline SrFe12 xAlxO19 (0rxr12), were prepared by the auto-combustion method and heat treated in air at 1100 1C for 12 h. The phase identification of the powders performed using x-ray diffraction show presence of high-purity hexaferrite phase and absence of any secondary phases. With Al3þ doping, the lattice parameters decrease due to smaller Al3þ ion replacing Fe3...
متن کاملSynthesis, structural and magnetic characterization of nanocrystalline nickel ferrite-NiFe2O4 obtained by reactive milling
Nanocrystalline nickel ferrite (NiFe2O4) has been synthesized from a stoichiometric mixture of oxides NiO and α-Fe2O3 in a high energy planetary mill. A post milling annealing at 350 °C was used to improve the solid state reaction. The obtained powders were investigated by X-ray diffraction, magnetic measurements, scanning electron microscopy, X-ray microanalysis, differential scanning calorime...

متن کاملSynthesis and characterization of Lanthanum doped Bismuth Ferrite
B1-xLaxFeO3 (x = 0.0, 0.025) crystallites were prepared by chemical solution route. XRD analysis confirmed the phase formation of the materials. Thermal characterization was done by DSC-TGA to confirm crystallization and thermal behavior for phase development. Morphological studies by FESEM showed the agglomerated nature of the ferrite...
