Abstract: Multiferroic BiFeO3 thin films were deposited on SrRuO 3-buffered quartz substrates by off-axis radio frequency magnetron sputtering. The BiFeO3 thin film exhibits the desired multiferroic behavior (2Pr ∼ 97.41 μC/cm2 and 2Ms ∼ 10.3 emu/cm3). On the basis of the temperature- and frequency-dependent impedance studies, oxygen vacancies are shown to be responsible for the dielectric relaxation and conduction in the BiFeO 3 thin film, where the scaling behavior of imaginary part of the electric modulus suggests that the relaxation mechanism does not change over the temperature range investigated. © 2010 Elsevier B.V.
