Structural and Microwave Properties of Copper Ferrite Nanoparticles Prepared by Sol-Gel Synthesis

Copper ferrite nanoparticles are prepared by sol-gel synthesis using polyacrylic acid (PAA) as chelating agent. The crystal structure and surface morphology are studied by XRD and SEM techniques. Microwave dielectric parameters such as real and imaginary part of complex permittivity and a.c. conductivity are determined in the frequency range 2247 - 2970 MHz by microwave cavity perturbation technique. Microwave magnetic parameters such as the real and imaginary part of complex permeability are also determined.
