Magnetic Properties of Cobalt Ferrite synthesized by Hydrothermal and Co-precipitation Methods: A Comparative Study

The magnetic properties of calcined cobalt ferrite formed by nano-crystalline powders have been compared by two different methods (co-precipitation and hydrothermal). The structural properties of the produced powders were investigated by X-ray Diffraction (XRD), scanning electron microscopy (SEM). The results show that the formation of cobalt ferrite spinel structures is effected by changing me...

Synthesis of cobalt ferrite nanoparticles using a combination of the co-precipitation and hydrothermal methods

In this work we have examined the influence of the pH on the structural and magnetic properties of cobalt ferrite (CoFe2O4) nanoparticles obtained by a combination of the co-precipitation and hydrothermal methods. The crystal structures and the particle sizes of the prepared powders were analyzed by the X-ray diffraction and transmission electron microscopy, while the magnetic properties of the...

Structure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method

Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer  (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...

pH and Properties of Synthesized Barium Hexa-Ferrite by Co-precipitation Method

Synthesis of BaFe12O19 magnetic nano particles via precipitation in different pH conditions have been reported. The certain molar ratio of Fe/Ba = 12 selected and sodium hydroxide was used as a precipitant agent. X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and vibrating sample magnetometer (VSM) were used to consider the structural, morphological and magnetic properties of bariu...
