Zirconium doped Nickel-Zinc ferrites of composition Ni0.7+xZn0.3ZrxFe2-2xO4 were prepared by standard double sintering ceramic technique. The single-phase cubic spinel structures of the samples were confirmed from X-ray diffraction patterns. Electrical properties namely DC-resistivity as a function of temperature were studied for ferrite samples. Dielectric properties such as dielectric constant (έ), dielectric loss (ε״) and loss tangent (tanδ) have been investigated at constant frequency with varying temperature.
