Synthesis of Cobalt Ferrite Nanoparticles: Characterization and Magnetic Properties.

Abstract: In this study, Cobalt ferrite nanoparticles (CoFe2O4) were synthesized via hydrothermal technique at 180˚C for 6h using pomegranate fruit peels extract have been investigated. The structural properties of the produced cobalt ferrite nanoparticles were investigated using X-ray diffraction (XRD). The average grain size (D) measured using Scherrer equation is 25.35nm. Fourier Transform Infrared spectroscopy confirmed the formation of cobalt ferrite nanoparticles particles. Magnetic hysteresis was measured using a vibrating sample magnetometer in a maximum field of 15 kOe. The magnetic properties of synthesized nanoparticles were reported such as saturation magnetisation (Ms), coercivity (Hc), and retentivity (Mr) at room temperature. Cobalt ferrite nanoparticles exhibited super-paramagnetic behaviours.
