Summary: The cobalt doping on bismuth nickelate synthesized by sol-gel method results in significant morphological transformations with crystallite sizes in the range of 42-60 nm. The dielectric properties are consistent with Koop's theory, with relaxation process deviation from ideal Debye-type behavior, and magnetization measurements showing paramagnetic behavior. Impedance analysis provides an accurate depiction of the electrical behavior, indicating potential scientific and industrial applications in sensors and memory devices for the cobalt-doped bismuth nickelate ceramics.
