Effect of CoFe2O4 on Dielectric and Conduction Behavior Pb0.75La0.25TiO3 Based Composites

(1-x) (Pb0.75La0.25TiO3)-x (Co2FeO4) where x = 0.50 & 0.60 Ceramic Composites have been successfully synthesized via mechanical mixing method. The substitution of CoFe2O4 with La3+ modified Lead Titanate (Pb0.75La0.25TiO3) in above mentioned stoichiometric proportions on has been explored for temperature dependent electrical properties. The both real and imaginary parts of dielectric permittivity decreases with increasing both temperature as well as ferrite content. The real part of impedance decreases with increasing temperature as well as Co2FeO4 content whereas maxima in imaginary part reveals the presence of temperature dependent dielectric relaxation. Both conductivity as well as dielectric loss increases with increase in Co2FeO4 content in stoichiometric proportion.
