Cobalt ferrite nano-powder have been obtained through a hydrothermal method with 2:1 molar ratio of Fe:Co without using any surfactant. X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used to consider the structural and morphological properties of CoFe2O4 nano-particles. Also, EDAX spectroscopy applied to evaluate the chemical composition. Results demonstrated that 15 hr hyd...

We identify contributions to the valence band of the nanosized BaFe12−2xCoxTixO19 barium ferrite particles, from the cobalt and titanium dopants. Resonant photoemission results show that cobalt and titanium dopants strongly hybridize with the barium ferrite matrix. Fano resonances are identifi ed in the valence band region, at the Ba (5s), Ti (3p) and Co (3p) thresholds, and there are signifi c...

The calcium ferrite nano-particles (CaFe2O4 NPs) were synthesized using a sol-gel method for targeted drug delivery application. The proposed nano-particles were initially prepared by mixing calcium and iron nitrates that were added with citric acid in order to prevent agglomeration and subsequently calcined at a temperature of 550°C to obtain small particle size. The prepared nanoparticles wer...

The effect of Cerium and Cobalt substitution in Zinc ferrites with respect to their electrical and magnetic properties has been investigated in this paper. The nanoparticles of Zn1-x-y Cex Coy Fe2O4 ( x = 0.012, 0014, 0.016, 0.018; y = 0.01, 0.001, 0014, 0.016) is prepared by sol gel route and sintered in a microwave furnace. The nano size, structure and composition of Ce-Co doped Zinc ferrite ...

Composite material based on Fe3Si micro-particles and Mn-Zn nano-ferrite was prepared using powder metallurgy technology. The sol-gel followed by autocombustion process was used for synthesis of Mn0.8Zn0.2Fe2O4 ferrite. 3 wt.% of mechanically milled ferrite was mixed with Fe3Si powder alloy. Mixed micro-nano powder system was homogenized by the Resonant Acoustic Mixing using ResodynLabRAM Mixer...

The magnetic properties of cobalt ferrite-silica nanocomposites with different concentrations (15, 30, and 50 wt %) and sizes (7, 16, and 28 nm) of ferrite particles have been studied by static magnetization measurements and Mossbauer spectroscopy. The results indicate a superparamagnetic behavior of the nanoparticles, with weak interactions slightly increasing with the cobalt ferrite content a...

Cobalt-ferrite (CoFe2O4) based materials are suitable candidates for magnetomechanical sensor applications owing to a strong sensitivity of their magnetostriction to an applied magnetic field. Zn-doped cobalt-ferrites, with nominal compositions CoFe2−xZnxO4 (x = 0–0.3), were synthesized by auto-combustion technique using Co, Fe, and Znnitrate as precursors. X-ray spectra analysis and Transmissi...
