Abstract

The distinct compositions of Co1-xCdxFe2O4 (x= 0.0, 0.1, 0.2, 0.3, 0.4, 0.5) samples were prepared by using sol-gel auto combustion method characterized to understand their physical and magnetic properties.The X-ray diffraction (XRD) analysis shows the existence of single phase cubic spinel structure with increase of lattice constant as Cd content increases. The bulk density, X-ray density, porosity, bond length and hopping length are exhibit similar behaviour. The particle size (< 33 nm) obtained from the Scherrer formula and linear intercept method using scanning electron microscope (SEM) confirms the nanocrystaline nature. Infrared (IR) shows two main absorption band corresponds to (A) and [B] site in spinel structure.
