Structural and Magnetic Studies of Co_0.6Zn_0.4Fe₂O₄ Nanoferrite Synthesized by Solution Combustion Method

Abstract

Co0.6Zn0.4Fe2O4 nanomagnetic system is prepared by solution combustion method. The powder sample is characterized by X-ray diffraction (XRD), transmission electron microscope analysis (TEM), Fourier transform infrared spectroscopy (FTIR), Mössbauer spectroscopy, and superconducting quantum interference device (SQUID; at low and room temperatures). The average crystallite sizes of the prepared samples obtained from XRD is 22 nm, which is well confirmed by the size obtained from TEM. The magnetic study shows that sample is ferromagnetic at room temperature. This result is also supported by Mössbauer spectrum obtained at room temperature.
