| Abstract: | (Na₀․₅Bi₀․₅)(Zr₀․₂₅Ti₀․₇₅)O₃, having perovskite-type orthorhombic structure, is prepared using via high-temperature solid-state reaction technique. The electrical behaviour has been assessed by electric modulus, pseudo Cole-Cole, and ac conductivity analyses. Electric modulus and pseudo Cole-Cole analyses indicated the dielectric relaxation to be of non-Debye type. The electrical conductivity studies showed the negative temperature coefficient of resistance character of (Na₀․₅Bi₀․₅)(Zr₀․₂₅Ti₀․₇₅)O₃. The ac conductivity is found to obey the universal power law and correlated barrier hopping model is found to successfully explain the electrical conduction in the system. |
