NiFe2O4 (nickel ferrite), ZnFe2O4 (zinc ferrite) and Ni0.5Zn0.5Fe2O4 (nickel-zinc ferrite) were prepared by mechanochemical route in a planetary ball mill starting from mixture of the appropriate quantities of the Ni(OH)2/Fe(OH)3, Zn(OH)2/Fe(OH)3 and Ni(OH)2/Zn(OH)2/Fe(OH)3 hydroxide powders. In order to monitor the progress of chemical reaction and confirm phase formation, powder samples obtai...

Nanoscale ferrimagnetic particles have a diverse range of uses from directed cancer therapy and drug delivery systems to magnetic recording media and transducers. Such applications require the production of monodisperse nanoparticles with well-controlled size, composition, and magnetic properties. To fabricate these materials purely using synthetic methods is costly in both environmental and ec...


 The soft chemical method was adopted to prepare of cobalt-substituted nickel-zinc ferrites (Ni0.95-x Zn0.05COx Fe2O4 for x = 0.01, 0.02 and 0.03). We have recently studied their structural, morphological, magnetic properties, initial permeability, dielectric constant. They were found be with cubic ferromagnetic spinel structure, the morphology which is suitable high-density recording med...

The soft chemical method was adopted for the synthesis of cobalt substituted nickel-zinc and zinc-nickel ferrites (Ni0.95-xZn0.05CoxFe2O4 Zn0.95-xNi0.05CoxFe2O4 x= 0.01, 0.02, 0.03, 0.04, 0.05, 0.06. We have recently studied structural, morphological, magnetic properties, initial permeability, dielectric constant samples. They are found with cubic ferromagnetic spinel structure along morphology...

We have studied the integration of Ni-Cu-Zn ferrite spinels as well as substituted hexagonal Co2Y-and M-type ferrites into LTCC (Low Temperature Ceramic Co-firing) modules. The cofiring behavior and the magnetic properties of these materials were investigated and evaluated for multilayer applications. Ni-Cu-Zn ferrites exhibit permeabilities of μ = 300 – 500 for operating frequencies in the MHz...

We report on the enhance magnetic properties of synthesized Mg-Ferrite catalyst through microwave-assisted combustion route by making nanocomposite via Zn-ferrite. The gravimetric oil removal capability tests from water at room temperature were performed. Phase impurity and surface morphology which investigated with XRD analysis field emission- scanning electron microscopy, indicate that spinel...
