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.
Keywords: Sol-gel, X-ray diffraction, Lattice constant, Nanoferrite.
