|Title in Arabic||AC Conductivity and Dielectric Properties of Cu–Zn ferrites|
In this work, we have studied the effects of the 2 Zn ions on the electric and the dielectric properties of the Cu spinel ferrite. The mixed Cu-Zn spinel ferrite, of chemical formula 1 s s 2 4 Cu Zn Fe O , where s stepped by 0.2 according to ( 0.0 s 1.0), were prepared from purity metal oxides using the standard ceramic preparation. The AC conductivity was determined for the ferrite samples in the applied frequency range (10 10 )Hz 4 6 . In this range of frequency, the AC conductivity increases rapidly as a function of the applied frequency. The dielectric properties for the ferrite samples were also determined at room temperature. The general trend for all samples was found to decrease continuously with increasing of the applied frequency. The measurements of the electric and the dielectric properties show that, the behavior of the ferrite samples is similar to that of the semiconductor materials. The results of the electric and dielectric properties are inadequate to previous studies for various ferrite compounds. The electric conductivity for the samples was explained using the electron hopping model.
