“…Consequently, CaRuO 3 requires a larger applied strain to switch its unit cell from orthorhombic to tetragonal. Other related studies have been carried out by Ito, Masumoto, and Goto (2009), who grew SrRuO 3 , CaRuO 3 , and BaRuO 3 on LaAlO 3 and observed both small surface roughness and high conductivity with the CaRuO 3 films, which have the best lattice match with the substrate material.…”

SrRuO 3 is endowed with three remarkable features. First, it is a moderately correlated material that exhibits several novel physical properties; second, it permits the epitaxial growth of essentially single-crystal films; and third, because it is a good conductor, it has attracted interest as a conducting layer in epitaxial heterostructures with a variety of functional oxides. In this review, the present state of knowledge of SrRuO 3 thin films is summarized. Their role as a model system for studying magnetism and electron transport characterized by intermediate electron correlation and large magnetocrystalline anisotropy is demonstrated. The materials science of SrRuO 3 thin film growth is reviewed, and its relationship to electronic, magnetic, and other physical properties is discussed. Finally, it is argued that, despite all that has been learned, a comprehensive understanding of SrRuO 3 is still lacking and challenges remain.American Physical Society

BRO thin films prepared on (001) STO and (001) LAO substrates tended to grow with the (205) orientation, and had an orthogonal texture.…”

Epitaxial BaRuO3 (BRO) thin films were prepared on (001) and (111) MgO substrates by laser ablation, and the relationship of lattice matching, morphology and electrical conductivity was investigated. (205)-and (001)-oriented rhombohedral BRO thin films were epitaxially grown on (001) and (111) MgO substrates, respectively. The (205) BRO thin films showed an orthogonal texture with faceted island grains, whereas the (001) BRO thin films had a hexagonal columnar structure with a flat terrace. Epitaxial BRO thin films showed metallic conduction, and the (205) BRO thin films exhibited the highest electrical conductivity, i.e., 1.0 × 10 5 S·m -1 , at room temperature. A higher lattice matching between epitaxial thin film and the substrate yielded a higher electrical conductivity.

“…CRO was chosen as bottom electrode material not only because of its high electrical conductivity in comparison with widely used SrRu03, [11] but also because its lattice similarity with LSAT and BFOLM (rhombohedral, a = 3.959 A), as CRO can be interpreted as a pseudo-cubic perovskite structure with a ;::: 3.85 A under constrained environment of epitaxial growth on a cubic substrate.

Orientation engineered (La, Mn) co-substituted BiFe03 [BFOLMI thin films were deposited on CaRu03 buffered (LaAI03)O.3(Sr 2 AITa06)O.35 (LSATI (0011, (110J and (111J single crystal substrates, respectively, by pulsed laser deposition.Highly epitaxial growth and sharp interfaces of the BFOLM ICaRuO;y'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 Pr were found to be 65,92, and 106 }lC/cm 2 for the (0011, (1101 and (1111-oriented films, respectively. While the largest saturated magnetic moment M, was along (0011 direction with the value of -12.8 emu/cm 3 . Anisotropic dielectric behaviors were also observed in differently oriented BFOLM thin films.
