The nickel zinc ferrites have semiconductor behaviour because resistivity of ferrites decreases with the increase of temperature. The electrical properties of NiZn ferrite NiZnFe4O4 were investigated by impedance spectroscopy over the frequency 1 Hz to 10 MHz at room temperature. Nickel Zinc Iron Oxide (NiZnFe4O4) Nanopowder ranging 20-30 nm in diameter has been characterized by Scanning electron Microscopy (SEM) and Raman Spectroscopy. The surface morphology of the studied compound has been investigated by Scanning Election Microscopy (SEM) indicating the homogeneous particle size and characteristic range of diameters 20-30 nm. Further, the Raman shift variation with the intensity which shows of studied compound has been analysed by Raman Spectroscopy.in which peak obtained at 330 cm-1, 483 cm-1, 691 cm-1 and 1328 cm-1 using laser at 785 nm. The electrical studies of the Nickel Zinc Iron Oxide (NiZnFe4O4) Nanopowder have been examined in order to acquire the electrical parameters (mainly dielectric permittivity, loss, conductivity, loss-tangent, impedance, and admittance).Appreciable rise in the conductivity (with frequency dependent) has been observed due to the decrease in the grain size i.e. nanoscale of the material. It is also observed that the relative permittivity ('), relative loss ('') and dissipation factor (Tan ) decreases with increase in frequency.
