Structure and magnetic properties of Cd doped copper ferrite

resumo

This report presents the synthesis of copper cadmium ferrite (Cu1-xCdxFe2O4, x = 0.3, 0.4, 0.5, 0.6 and 0.7) by citrate precursor method and its subsequent characterization by using X-ray diffraction ( XRD), electron diffraction spectroscopy (EDS) and vibrating sample magnetometer (VSM) techniques. XRD results confirm the single cubic spinel phase formation with the particle size of 40 nm, which decreased up to 20nm with increases in Cd content, while the lattice parameter increased with increase in Cd content. By using VSM technique, a significant change in the magnetic properties was observed in CuFe2O4 system with Cd doping. It is seen that magnetic field H-C and remnant magnetization M-R increases with increasing concentration up to x = 0.6 except for x = 0.4 and 0.7. (C) 2011 Elsevier B.V. All rights reserved.
