Abstract: Orientation engineered (La, Mn) co-substituted BiFeO3 [BFOLM] thin films were deposited on CaRuO3 buffered (LaAlO3) 0.3(Sr2AlTaO6)0.35 [LSAT] [001], [110] and [111] single crystal substrates, respectively, by pulsed laser deposition. Highly epitaxial growth and sharp interfaces of the BFOLM /CaRuO3/LSAT heterostructures were revealed by x-ray diffraction and high resolution transmission electron microscopy. Their ferroelectric and ferromagnetic properties are strongly dependent on the crystallographic orientation. At 1 kHz and room temperature, the remanent polarization P r were found to be 65, 92, and 106 μC/cm2 for the [001], [110] and [111]-oriented films, respectively. While the largest saturated magnetic moment Ms was along [001] direction with the value of ∼ 12.8 emu/cm3. Anisotropic dielectric behaviors were also observed in differently oriented BFOLM thin films.
