Cd content dependent magnetic properties of Li0.5-x/2 Cdx Fe2.5-x/2O4 nano-ferrite prepared without post preparation thermal treatment

Résumé

Nano-crystalline Li 0.5-x/2 Cd x Fe 2.5-0.5/2 O 4 , (x = 0.0, 0.11, 0.22, 0.33, 0.44), were synthesized by sol gel auto combustion method without post preparation thermal treatment. Effect of Cd content on structural, magnetic properties has been studied by x-ray diffraction (XRD), magnetic measurements. XRD validates the formation of spinel ferrite, with Scherrer's grain diameter ranging between 16.7 nm-28.95 nm. Coercivity (H c) and anisotropy constant (K 1) values respectively ranges` between 115.13 to 178.71 Oe and 1.86×10 4 to 3.68×10 4 erg/cc. Best magnetization of 56.77 Am 2 /kg was obtained for x = 0.44, observed variation of magnetic properties is explained in terms of observed changes in cation distribution.
