    • Abstract

       

      Dense and stoichiometric $\rm{Ba_{0.8}Mg_{0.2}(Zr_{0.1}Ti_{0.8}Ce_{0.1})O_{3} (BMZTCO)}$ ceramics have been synthesised and their excitation was experimentally evaluated by applying an electric field. The processed sample exhibits superior frequency-independent and temperature-dependent dielectric parameters. The prepared sample has combined the tetragonal and cubic phases of $\rm{BaTiO_{3}}$ and $\rm{Ce_{2}O_{3}}$. The Bode plots suggest non-Debye type of relaxation mechanism and positive temperature coefficient-type behaviour. The excitation intensity reaches a peak when the driving frequency matches with the natural frequency of the prepared sample.
