Abstract

Zink cobalt ferrite (Co0.5Zn0.5Fe2O4) were synthesized using sol-gel auto combustion method. The synthesized particles were characterized using X-ray diffraction, the XRD patterns corresponding to spinel crystalline (Co0.5Zn0.5Fe2O4). Dielectric permittivity ( ) of Co0.5 Zn0.5 Fe2O4 decreases while conductivity (σ) increases with increasing frequency. The samples have high values of ε’ at low frequencies. The D.C electrical resistivity was investigated from room temperature to 423 K, the variation of dc conductivity decreases by increasing temperature hence resistivity increases.

Keywords: Co-Zn ferrites; sol gel auto combustion; X-ray Diffraction; dielectric behavior; dc conductivity

Article published in International Journal of Current Engineering and Technology, Vol.6, No.1 (Feb-2016)
