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

“…Moreover, these materials have been investigated for their potential as promising candidates for the next generation of electronics due to their dual eddy and magnetization properties. 12–14 Additionally, perovskite oxides at room temperature can exhibit a variety of crystalline structures, such as cubic ( Pm 3), tetragonal ( I 4/ m ), monoclinic ( P 2 1 / n ), and rhombohedral ( R 3 c ) systems. 15–17 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.…”

“…M* = = (jw Z* = M' = w Z' + M''= w Z'' (9) Where C 0 is the cell's vacuum capacitance. The electrical modulus' real M' component is depicted in Fig.…”

“…Indeed, double perovskite oxides present a variety of crystalline structures at room temperature, their structures can be: cubic (Pm-3m), for example LaBa 0.5 Ag 0.5 FeMnO 6 [9], tetragonal (I4/m) like Sr 2 CoWO 6 [10], monoclinic (P2 1 /n) like Ca 2 FeMoO 6 [11] and rhombohedral system (R C) like BiBaFeZnO 6 [12] and LaPbFeTiO 6 [13]. Among the double perovskite materials, the oxides of general formula A'A'B'B'O 6 (A'=La, Bi, Sr), (A''=Ba), (B'=Ni) and (B'=Nb, Mn, Fe), such as the oxide BiBaFeZnO 6 [12].…”

Insights into dielectric and electrical conductivity dynamics in sol-gel synthesized Ba0.75Ni0.25Tc0.88Mn0.12O3 perovskite ceramic

“…Fixed-frequency Curie-Weiss plots indicated deviations from linearity at temperatures well above T c . The ac measurements revealed that grain boundary impedances impact Curie-Weiss plots in two ways: at high temperatures, they increasingly dominate fixed-frequency permittivity, while at lower temperatures closer to T c , the high-frequency permittivity contains a contribution from grain boundary effects [22][23][24][25][26][27][28][29].…”
