Abstract

Pr and Mn co-substituted BiFeO3 (BFO) thin films were fabricated on a Pt-coated (100) SrTiO3 substrates by pulsed laser deposition (PLD) method. X-ray diffraction patterns indicated that the formation of impurity phases was suppressed by Pr substitution in the BFO thin films. Furthermore, by combining with small amount of Mn substitution, Pr substitution was effective for reducing the leakage current density. The polarization vs electric field curves showed well-saturated hysteresis loops with measurement frequency of 20kHz at room temperature. The remnant polarization at a maximum electric field of 1500 kV/cm was approximately 50-70 μC/cm2.
