Luo, H. Or, S.W. Wang, Y. Chan, H.L.W. Faculty Aerospace Engineering Date 2009-06-26 Abstract Perovskite oxide Pb(Fe1/2Nb1/2)0.52Ti0.48O3 crystals, which were grown using a modified Bridgman method, show a high low-frequency dielectric constant response at room temperature. The Curie phase transition occurs at 523 K. The characteristic frequency of the dielectric dispersion versus the inverse of temperature obeys an Arrhenius relation, which shows a thermally activated behavior. The thermal activation energy for relaxation was found to be ? 0.14?eV. The high dielectric permittivity was attributed to oxygen vacancies and conduction via hopping carriers.
