Dielectric properties such as dielectric constant,and dielectric loss factor, tan are reported for different compositions of
NiZn ferrites prepared by the citrate precursor method and sintered in the temperature range 1100–1400°C. It is observed that and tan for samples prepared in the present work are much lower than those normally obtained for NiZn ferrites prepared by the conventional ceramic method. The low values are attributed to better compositional stoichiometry, single-phase spinel structure and uniform microstructure of the samples. The low dielectric loss makes these samples especially attractive for use at high frequencies.
