Role of Nd-Ni on structural, spectral and dielectric properties of strontium-barium based nano-sized X-type ferrites

The influence of neodymium (Nd) contents on the structural, electrical and dielectric properties of Nickel cobalt ferrites was studied in the ferrite series NixCO1-xNdyFe2-yO4 (x= 0.00, 0.20, 0.40, 0.60, 0.80, 1.0 and y = 0.00, 0.02, 0.04, 0.06, 0.08, 0.1). This series was prepared by sol-gel method. XRD analysis reveals single phase samples up to y=0.04. At y ≥ 0.06, a secondary phase of iron neodymium oxide (NdFeO3) appears along with the spinel phase. The incorporation of Nd 3+ for Fe 3+ ions results in a slight increase of lattice constant due to larger ionic radius of the substituted ions. It was inferred that the substitution of neodymium limits the grain growth. The DC electrical resistivity and activation energy are higher for the substituted samples. The dielectric constant, dielectric loss (tan δ) and AC-conductivity decreased on account of doping. The decrease in dielectric constant is imputed to the reduction in the internal viscosity of the doped samples. The dielectric data are explained on the basis of space charge polarization. Ferrites have high dielectric constant and low tan δ, they may be attractive for application in switching and memory storage devices.
