Abstract: The dielectric permittivity and dissipation factor of La-doped and undoped BaTiO3 were investigated as a function of frequency and temperature. The impedance response was used to study the electrical properties of La-doped BaTiO3 over the temperature range from room temperature (RT) to 350°C. La-doped and undoped BaTiO3, obtained by a modified Pechini method, were sintered in air at 1300°C for 2 and 16 hours. The impedance spectra were analyzed in terms of equivalent circuits involving resistors, capacitors and constant phase elements (CPE). The most suitable electrical circuit for the interpretation of experimental results is found to be the equivalent circuit consisting of resistors and CPE elements which replace the capacitor elements. The contribution of grain boundary resistance to the total resistance of a system is remarkable at low temperature. Dielectric permittivity of doped BaTiO3 was in the range of 8000 to 12000 at 1 kHz and the dissipation factor was less than 1%.

Impedance spectroscopy: Models, data fitting, and analysis
TL;DR: In this article, several impedance spectroscopy models found useful for data fitting and interpretation of dielectric and conductive-system frequency data are briefly summarized and compared, and it is concluded, on the basis of both experimental and synthetic data fitting, that the corrected modulus formalism approach, with a temperature and ionic-concentration independent fractional exponent, β 1C ≤ 1/3, is the most appropriate model for representing the hopping response of homogeneous materials; an effective medium nearlyconstant-loss model describes such experimental loss data well; and the
