In the present work, cadmium-substituted nickel ferrite with a general formula Ni1-xCdxFe2O4 (x=0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6) have been prepared by means of the low-temperature sol–gel technology with participation of autocombustion and are investigated for their electrical and dielectric properties such as dc resistivity rhodc, dc conductivity sigmadc, dielectric permeability epsilon, and dielectric loss tg(delta) as functions of Cd2+ concentration. The results for studied properties of the Ni1-xCdxFe2O4 ferrites are given in the temperature range 298–723 K and in the frequency range 10–2–106 Hz. As detected, the course of curves represented in Nyquist coordinates depends on temperature. As shown, with increasing temperature, conductivity of nickel–cadmium ferrites increases too. As determined, the activation energy EА of dc conductivity at high temperatures increases significantly. High-temperature EА is equal to 0.32–0.54 eV. This is due to a change in mechanism of conductivity in the temperature range 340–360 K for samples, which contain Cd2+ ions. The dependences of epsilon and tg(delta) on the frequency of the alternating applied electric field are in accordance with the Maxwell–Wagner model.

Key words: sol–gel technology, nickel–cadmium ferrite, dielectric permeability, specific conductivity, activation energy.
