Orbital Ordering in Orthorhombic Perovskites
Abstract
In addition to a cooperative MO6/2 site rotation, orthorhombic AMO3 perovskites with Pbnm space group have a universal, intrinsic MO6/2 site distortion consisting of an orthorhombic component and a reduction from 90° of the O–M–O bond angle α that subtends the octahedral-site edges parallel to the orthorhombic b axis. RMO3 perovskites (R = rare earth or Y, M = 3d-block transition metal) exhibit a maximum intrinsic orthorhombic site distortion at an R3+-ion radius IR ≈ 1.11 Å and a reduction of α that increases with IR > 1.11 Å. How the universal site distortions influence Jahn–Teller cooperative orbital orderings on the M cations is illustrated in four orthorhombic perovskite families: RTiO3, RVO3, RMnO3, and RNiO3.

LNO is the most relevant electrode material for oxide electronics due to relatively low electrical resistivity (100-1000 μOhm·cm) and lattice parameters close to many ferroelectric and multiferroic perovskites.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
