Exploring Relaxation Phenomenon in Cu-Substituted Ba2NiWO6 Double Perovskites

Double perovskites are an emerging class of functional materials with a great deal durability perspective owing to their inherent flexibility in cation coordination selection. Here, we synthesized pristine and Cu2+-doped Ba2NiWO6 utilizing the solid-state reaction route investigate structural, morphological, dielectric behavior. Structural examination revealed development cubic crystal structure for both compositions, Cu2+ integration decreases crystallite size. The spherical-shaped grains shrink size start agglomeration incorporation. incorporation reduces grain size, leads accumulation space charges at boundaries, thus, facilitates growth charge polarization. This increases constant material, thus making these compositions viable advanced miniaturized electronic devices.
