abstract={Ni substituted Li-Zn ferrites with compositional formula Li<SUB>0.4-0.5x</SUB>Zn<SUB>0.2</SUB>Ni<SUB>x</SUB>Fe<SUB>2.4-0.5x</SUB>O<SUB>4</SUB> where 0.02 ¡Ü x ¡Ü 0.1 in steps of 0.02 was fabricated by using citrate precursor method. X-ray diffraction was used to confirm the spinel phase. The dielectric constant was investigated as a function of composition, frequency and temperature. Room temperature dielectric constant showed a decrease with addition of Ni<SUP>2+</SUP> ions. It was explained in terms of space charge polarization and koops two layer model. The variation in dielectric constant with frequency showed dispersion. Variation of dielectric constant with temperature was studied at different frequencies and an increase was observed as temperature rises. The possible mechanisms responsible for the above behavior are explained.},
