Dielectric Relaxation Properties in Colossal Dielectric Constant Material Sr0.9Ba0.1Ti0.9Ru0.1O3
We investigated the colossal dielectric constant behavior and interesting dielectric relaxation over broad temperature and frequency ranges in complex perovskite Sr0.9Ba0.1Ti0.9Ru0.1O3 ceramics by using HP4294 impedance analyzer. Through the discussion, there exists a clear link between the dielectric relaxation and the sample conductivity. It’s believed that hopping of electrons between color centers not only produce conductivity but also give rise to dielectric relaxation behavior.
