Structural, dielectric and impedance spectroscopy analysis of Ba₅CaTi_1.94Zn_0.06Nb₈O₃₀ferroelectric ceramic

Abstract

ceramic. The variation of AC conductivity as a function of frequency reveals that the compound has an Arrhenius-type behavior of electrical conductivity. The DC electrical conductivities of grains and grain boundaries have been studied. The presence of non-Debye relaxations was verified by a complex modulus analysis.
