Synthesis, Characterization and Magnetic Properties of Co2+ Substituted Ni Nanoferrite by Sol-Gel Autocombustion Method

Abstract

Cox Ni1-x Fe2 O4 (x= 0.5, 0.7, 0.9) nanoferrite powder were prepared using a simple cost effective, solgel autocombustion method at low temperature. Metal nitrates are used analytical grade, such as Nickel nitrate, Cobalt nitrate and ferric nitrate, were used as the source materials. Citric acid was used as the burning agent and the metal nitrate- to -citric acid taken as ratio 1:3. The pH of the precursor was maintained at 7. The synthesized powder was characterized by TGA/DTA it shows that the phase formation, The FTIR spectroscopy is used to deduce the structural investigation and confirmation of ferrite, The X-ray diffraction (XRD) was used to determine the particle size and structural properties. The Vibrating Sample Magnetometer (VSM) was used to obtain the Hysteresis parameters. The magnetic property of the samples shows remarkable changes with change of Co 2+. The variation of Co2+ substitution has a significant influence on the grain size and magnetic properties. The mean crystalline size of the prepared ferrite was in the range of ~ 36 - ~45 nm.
