New Technique to Make Ferrite Nanosized Particles
Preparation of magnetitelmaghemite nanometric particles is reported from the precipitation of ferrous dodecyl sulfate micellar solution with methylamine. The size of nanocrystals is controlled by the micellar concentration and by temperature. It varies from 3.3nm to llnm. Magnetic properties are studied for various sizes of maghemite particles.
متن کاملA novel method to fabricate CoFe2O4/SrFe12O19 composite ferrite nanofibers with enhanced exchange coupling effect
Nanocomposite of CoFe2O4/SrFe12O19 has been synthesized by the electrospinning and calcination process. A novel method that cobalt powder was used to replace traditional cobalt salt in the precursor sol-gel for electrospinning was proposed. The crystal structures, morphologies, and magnetic properties of these samples have been characterized in detail. Moreover, when the average crystallite siz...
متن کاملHRTEM and FTIR investigation of nanosized zinc ferrite irradiated with 100 MeV oxygen ions.
Present work aims to investigate effect of 100 MeV oxygen ion irradiation on the vibrational modes of zinc ferrite nanoparticles. Nanosize zinc ferrite systems of different crystallite size ranging from 12-62 nm were irradiated at the fluence of 1×10(13) and 5×10(13) ions/cm(2). High resolution transmission electron micrograph study indicates the structural disorder induced by ion irradiation. ...
متن کاملPVP-Assisted Synthesis of Cobalt Ferrite (CoFe2O4) Nanorods
Cobalt ferrite (CoFe2O4) nanorods were synthesized by iron chloride (FeCl3.6H2O) and cobalt sulfate hexahydrate (CoSO4.7H2O) as precursor in the presence of ethylene glycol agent and poly vinyl pyrrolidone (PVP) surfactant. The samples were characterized to identify the physical properties. XRD pattern of cobalt ...
