Energetics of oxygen-octahedra rotations in perovskite oxides from first principles
Peng Chen, Mathieu N. Grisolia, Hong Jian Zhao +5
We use first-principles methods to study oxygen-octahedra rotations in ABO3 perovskite oxides. We focus on the short-period, perfectly antiphase or in-phase, tilt patterns that cha…
Origin of the orbital and spin orderings in rare-earth titanates
Julien Varignon, Mathieu N. Grisolia, Daniele Preziosi +2
Rare-earth titanates RTiO are Mott insulators displaying a rich physical behavior, featuring most notably orbital and spin orders in their ground state. The origin of their fer…
Hybridization-controlled charge transfer and induced magnetism at correlated oxide interfaces
M. N. Grisolia, J. Varignon, G. Sanchez-Santolino +11
At interfaces between conventional materials, band bending and alignment are classically controlled by differences in electrochemical potential. Applying this concept to oxides in…
Structural, magnetic, and electronic properties of GdTiO3 Mott insulator thin films grown by pulsed laser deposition
M. N. Grisolia, F. Y. Bruno, D. Sando +6
We report on the optimization process to synthesize epitaxial thin films of GdTiO3 on SrLaGaO4 substrates by pulsed laser deposition. Optimized films are free of impurity phases an…
Reconciling the ionic and covalent pictures in rare-earth nickelates
Julien Varignon, Mathieu N. Grisolia, Jorge Íñiguez +2
The properties of AMO3 perovskite oxides, where M is a 3d transition metal, depend strongly on the level of covalency between the metal d and oxygen p orbitals. With their complex…
Imaging flux distributions around superconductors: Geometrical susceptibility in the Meissner state
Mathieu Grisolia, Antonio Badia-majos, Cornelis Jacominus Van Der Beek
Experiment and analytical calculations show that the demagnetizing field of a superconductor is a sensitive probe of quantities otherwise difficult to measure, such as the sample-p…
