Suppression of octahedral tilts and associated changes in electronic properties at epitaxial oxide heterostructure interfaces.
Epitaxial oxide interfaces with broken translational symmetry have emerged as a central paradigm behind the novel behaviors of oxide superlattices. Here, we use scanning transmission electron microscopy to demonstrate a direct, quantitative unit-cell-by-unit-cell mapping of lattice parameters and oxygen octahedral rotations across the BiFeO3-La0.7 Sr0.3 MnO3 interface to elucidate how the chang...
متن کاملControl of octahedral tilts and magnetic properties of perovskite oxide heterostructures by substrate symmetry.
Perovskite transition-metal oxides are networks of corner-sharing octahedra whose tilts and distortions are known to affect their electronic and magnetic properties. We report calculations on a model interfacial structure which avoids chemical influences and show that the symmetry mismatch imposes an interfacial layer with distortion modes that do not exist in either bulk material, creating new...
متن کاملCharge-stripe ordering from local octahedral tilts: Underdoped and superconducting La22xSrxCuO4 „0<x<0.30..
The local structure of La22xSrxCuO4 , for 0<x<0.30, has been investigated using the atomic pair distribution function ~PDF! analysis of neutron powder-diffraction data. The local octahedral tilts are studied to look for evidence of @110# symmetry @i.e., low-temperature tetragonal ~LTT! symmetry# tilts locally, even though the average tilts have @010# symmetry @i.e., low-temperature orthorhombic...
متن کاملStructural and electronic correlations
Induction of glutathione transferases (EC. 2.5.1.18), NAD(P)H: (quinone-acceptor) oxidoreductase (EC 1.6.99.2; quinone reductase) and other detoxification enzymes is a major mechanism for protecting cells against the toxicities of electrophiles, including many carcinogens. Although inducers of these two enzymes belong to many different chemical classes, they nevertheless contain (or acquire by ...
متن کاملElectronic Structure Investigation of Octahedral Complex and Nano ring by NBO Analysis: An EPR Study
To calculation non-bonded interaction of the [CoCl6]3- complex embedded in nano ring, we focus on the single wall boron-nitride B18N18 nano ring. Thus, the geometry of B18N18 nano ring has been optimized by B3LYP method with EPR-II (Electron paramagnetic resonance) basis set and geometry of the [CoCl6]3- complex has been optimized at B3LYP method with Aldrich’s VTZ basis set and Stuttgart RSC 1...
