Abstract: Bi (Sc0.5 Fe0.5) O3 - PbTiO3 (BSF-PT) thin films with a composition in the vicinity of a morphotropic phase boundary (MPB) between rhombohedral and tetragonal phases have been grown on LaNiO3 / SiO2 /Si substrates at 550 °C and 150 mTorr by pulsed laser deposition. The dielectric properties of the film were enhanced due to high crystallinity, low porosity, and the vicinity of the MPB. A saturated ferroelectric hysteresis loop was obtained with 2 Pr =76 μC/cm, and the leakage current was minimized by cooling the samples, postdeposition in O2. Magnetic measurements revealed that BSF-PT thin films were antiferromagnetic confirming their anticipated multiferroic nature. © 2009 American Institute of Physics.
