PbTiO₃ (Pb1-xGdxTiO₃, x = 0.22 & 0.25) trivalent metal ion (Gd³⁺⁾ modified ferroelectric perovskites have been created utilizing solid solutions. The produced solid solution crystallizes in the tetragonal phase, according to structural analysis from x-ray diffraction, while S-shaped Polarization vs. Thermally activated dipoles stamped to customize the dielectric, conductive, and impedance response caused the hopping process. It has been examined and documented how the effect of hetrovalancy substitution results in the formation of oxygen vacancies, which enhance conductivity. The appearance of the relaxation phenomenon is clearly indicated by the peaks in the imaginary part of the electrical modulus. While a decrease in the real part of impedance and electric modulus indicates an increase in conducting response caused by an increase in the concentration of oxygen vacancies resulting from the charge imbalance created by substitution of Gd³⁺ at Pb²⁺ in PbTiO₃ ferroelectric ceramic solid solutions, an increase in the dielectric constant with increasing temperature directly indicates thermally activated dipoles.
