Abstract

The structural and magnetic properties of Cu-substituted, Co-Mg mixed nanoferrite synthesized by a sol-gel auto-combustion method are presented. Significant modifications in crystallite size, density, and grain size are observed with increasing Cu concentration. Comparable values of theoretical and experimental lattice parameters were obtained for all the Cu-substituted samples. Cation distribution estimated from X-ray intensity calculations shows that Cu influences the preferential site occupancy of Mg ions. It is found that Cu and Mg simultaneously occupy tetrahedral (A) and octahedral (B) sites with different ratios. The particle size calculated using TEM for undoped Co-Mg ferrite is about 80 nm. Saturation magnetization and permeability increase initially and reach a maximum value (x = 0.3) and then decrease. The observed variation is explained on the basis of redistribution of cations (Cu 2+ and Mg 2+) among the tetrahedral (A) and octahedral (B) sites. The initial permeability shows a good stability with increasing frequency.
