Multiferroic composite ceramics of x(Pb₀․₇₅Nd₀․₂₅TiO₃) - 1-x(NiFe₂O₄) where x = 0.50 and 0.40 have been synthesized using mechanical mixing method. For multiferroic composites synthesis, both ferroelectric and magnetic component have been prepared individually. The mechanical mixing of NiFe₂O₄ with Nd³⁺ modified lead titanate (Pb₀․₇₅Nd₀․₂₅TiO₃) in above mentioned stoichiometric proportions. The temperature dependent electrical properties such as dielectric permittivity, electrical impedance and conductivity have been explored. The effect of NiFe₂O₄ on electrical conductivity and conduction behavior of prepared ceramic composites has also been studied. The value of dielectric permittivity first increases upto certain value of temperature and then decreases. The decrease in value of real dielectric permittivity with first increases upto certain value of Temperature and then starts decreases. The conductivity increases with increasing temperature. The increase of oxygen vacancies due to temperature may results for uninterrupted increase in electrical conductivity.
