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

Abstract

_(1-x) (Pb_0.75La_0.25TiO₃)-_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 (Pb_0.75La_0.25TiO₃) 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.
