Abstract

The room temperature direct current (DC) resistivity of Ni_1-xZn_xFe₂O₄ (x=0.2, 0.3, 0.4 and 0.5) prepared by the non-conventional flash combustion and citrate-gel decomposition techniques have been studied. The high resistivity (ρ_dc) of the order of 10⁹ Ω cm is obtained and it has been found that there is reduction in resistivity with increase in zinc content and sintering temperature. The high resistivity values observed in the present work confirm that the dielectric constant of the samples should be low.
