In this article, Co1_xZnxFe2O4 (x¼0.0 and 0.5)spinel ferrite nanoparticles were achieved at 800 °C by starch-assisted sol–gel autocombustion method.To further reduce the particle size, the sesynthesized ferrite nanoparticles were ball-milled for 2h. X-ray diffraction patterns demonstrated single phase formation of Co1_xZnxFe2O4 (x¼0.0 and0.5) spinel ferrite nanoparticles. FE-SEM analysis indicated the nanosized spherical particles formation with spherical morphology.The change in Raman modes and relative intensity were observed due to ball milling and consequently decrease of particle size and ca- tionic redistribution. An X-ray Photoelectron Spectroscopy (XPS) result indicated that Co2þ, Zn2þ and Fe3þ exist in octahedral and tetrahedral sites. The cationic redistribution of Zn2þ and consequently Fe3þ occurred between octahedral and tetrahedral sites after ball-milling. The change in saturation magne- tization (Ms) and coercivity (Hc) with decrease of nanocrystalline size and distribution of cations in spinel ferrite were observed.
