Ni0.4Zn0.6Fe2O4 ferrites were prepared by the conventional solid-state method. The X-ray study allowed the identification of a single orthorhombic phase. The conductivity of the prepared sample was measured at different frequencies in the temperature range 340 K to 600 K. The obtained results are discussed in terms of charge carriers hopping. We showed that the dielectric permittivity is high at different temperatures and various frequencies. The impedance plane findings present semicircle arcs at various temperatures and an electrical equivalent circuit was determined. In addition, the obtained two relaxation times were established as a function of temperature.
