Dielectric and AC conductivity properties dependant simultaneously on T and ω of microwave sintered Ba0.997Pr0.003TiO3 ceramic: an experimental and simulation studies using modified Lorentz equations derived from Lorentz equation

In our earlier studies we have shown procedure for the estimation of activation energy and relaxation times directly from the dielectric and AC conductivity data simultaneously dependant on T and ω using modified Lorentz equation instead of well-known Arrhenius, modified Arrhenius and Vogel-Fulcher laws. In the present paper we have carried out similar experimental and simulation studies on the dielectric and AC conductivity data using modified Lorentz equations on the ceramic compound (Ba_0.997Pr_0.003TiO₃). The obtained results on the activation energy and relaxation times are presented in this paper. [ABSTRACT FROM AUTHOR]
