Dipolar glass state in BaCe0.3Ti0.7O3 perovskite solid solutions

Journal of Alloys and Compounds, 2021
An extensive broadband dielectric spectroscopy study of BaCe0.3Ti0.7O3 ceramics is presented. The distribution of relaxation times of the system derived from the frequency dependence of complex dielectric permittivity are similar to the ones observed in dipolar glasses.
