Abstract
In this study, the nanoparticles (NPs) of
Ni0.6Cu0.1Cd0.3Fe2O4 (NCCF) ferrite was successfully synthesized
by sol-gel auto combusted process. The effects of temperature
and size on the structural, dielectric and conductivity properties
of NCCF ferrite nanoparticles were investigated. X-ray
diffraction (XRD) analysis of the NPs annealed at 550 and 700 ÂșC
displayed the single phase cubic spinel structure with the particle
size of 11 and 17 nm, respectively. The surface morphology of the
annealed NCCF ferrite nanoparticles was studied by using field
emission scanning electron microscopy (FESEM). Dielectric
constant of larger particles shows higher values at low frequency
as well as lower dielectric loss tangent. Ac conductivity shows
conventional trend with size effects.
