摘要
DC, AC electrical resistivity (rho(dc) and rho(ac) (omega) and dielectric properties (epsilon' and tan delta) were studied for Zn0.8Co0.2Fe2O4 ferrite samples prepared at sintering temperatures (T-s) in the range 1273 to 1473 K by the usual ceramic technique. The experimental results indicated that the DC and AC electrical resistivity, Curie temperature (T-c) and activation energies for electrical conduction (E(p) and E(f)) decrease as the sintering temperature increases. The DC electrical conductivity increases as the temperature increases. It was found that epsilon', tan delta and rho'(ac), (omega) decrease as frequency increases.
