Processing and Characterization of Cobalt-Zinc Nano Ferrite

摘要

Co_(1-x)Zn_(x)Fe_(2)O_(4) (x velence 0.1, 0.2, 0.3, 0.4) nano magnetic systems were prepared by solution combustion method. The powder samples are characterized by x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Transmission electron microscopy (TEM), and Mossbauer spectroscopy. The average crystallite sizes of the prepared sample obtained from XRD are well consistent with particle size obtained from TEM images. Fourier transform confirm the spinel phase structure of cobalt zinc ferrite. Mossbauer spectra indicate that sample with 40percent zinc concentration exhibits the collective magnetic excitations.
