Investigation of Structural and Magnetic Properties of Cu1-xCdxFe2O4 Ceramic System

resumo

Polycrystalline samples of Cu1 - xCdxFe2O4(x = 0.3, 0.4, 0.5, 0.6 and 0.7) were prepared by citrate precursor method. X-ray diffraction results confirm the cubic spinel phase formation with an increase in the lattice parameter with increasing Cd content. Transmission Electron Micrographs show particle size of the samples to lie between 20 nm to 40 nm. By Vibrating Sample Magnetometer, the magnetization curves of the samples under the ZFC and FC conditions show a systematic change (increase) with x ratio. The effect of concentration (x) on magnetic properties is clearly perceptible in the evolution of hysteresis loop indicating that Cu1 - xCdxFe2O4 introduced ferromagnetic contribution.
