dc.description.abstract | Bismuth doped Cobalt ferrite nanoparticles has been prepared by sol-gel auto combustion method. Attempts have been made to study the electrical and magnetic transport properties of CoBixFe2-xO4 nanoparticles. The phase identification and morphological studies have been carried out by X-ray diffraction (XRD), Raman spectroscopy, Transmission electron microscopy (TEM) and Field emission scanning electron microscopy (FESEM). Obtained results confirm the presence of single phase spinal structure having space group Fd3m. In addition, spherical grains having diameters ranging from 20-30 nm has been detected through the FESEM and TEM micrographs. Further, Mossbauer study is conducted to observe the distribution of the cobalt and bismuth in the spinel ferrite. Magnetic susceptibility measurements both for MT and MH show the enhancement for saturation magnetization Ms and coreicivity Hc on the Bi substituted samples and with the irradiation. The isomer shift (δ), quadrupole splitting (Δ), and hyperfine field (Hf) corresponding to various concentration of Bi have been discussed with gamma irradiation. | en_US |
