Nickel Ferrite Nanoparticle Generation by Combustion Method and the Nanoparticle Structural and Magnetic Characterization and the Effect of Ball Milling

The combustion method has been utilized to generate nickel spinel ferrite nanoparticles. The nanoparticles were generated on two different molarities of Fe (NO₃)₃. 9 H₂O and Ni (NO₃)₂. 6 H₂O. The generated nanoparticles were ball milled for 3 h. Physical and chemical properties of the nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and a vibrating sample magnetometer. The crystalline structure of nanoparticles was stable after ball milling. Investigation of structural stability of ball-milled samples was done by XRD characterization. FTIR showed that oxygen-metal bonding was stronger after ball milling. Moreover, the ball-milled nanoparticles magnetically were harder than the nanoparticle without ball milling.
