Exploring bismuth-doped polycrystalline ceramic Ba0.75Bi0.25Ni0.7Mn0.3O3: synthesis, structure, and electrical properties for advanced electronic applications

“…[15][16][17] Among the double perovskite materials, the oxide BiBaFeZnO 6 , conforming to the general formula A ′ A ′′ B ′ B ′′ O 6 (A ′ = La, Bi, Sr, A ′′ = Ba, B ′ = Ni, B ′′ = Nb, Mn, Fe), has been synthesized using the sol-gel method, with dielectric, electrical, temperature, and frequency dependencies being investigated. 18 Furthermore, the complex electrical impedance analysis has provided insights into distinguishing true relaxation from non-Debye relaxation, supporting the concept that heat initiates the conduction process, as evidenced by the frequency dependence of electrical conductivity. 19 The present work aims to examine the structural and electrical properties of a Ba 0.75 Bi 0.25 Ni 0.7 Mn 0.3 O 3 (BNMO) sample synthesized using the sol-gel technology.…”
