Direct Observation of Charge Order in an EpitaxialNdNiO3Film
Open accessAbstract
The first direct observation of charge order of ${\mathrm{Ni}}^{3+{\ensuremath{\delta}}^{\ensuremath{'}}}$ and ${\mathrm{Ni}}^{3\ensuremath{-}\ensuremath{\delta}}$ by resonant x-ray scattering experiments in an epitaxial film of ${\mathrm{NdNiO}}_{3}$ is reported. A quantitative value of $\ensuremath{\delta}+{\ensuremath{\delta}}^{\ensuremath{'}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(0.45\ifmmode\pm\else\textpm\fi{}0.04)e$ was obtained. The temperature dependence of the charge order deviates significantly from those of the magnetic moment and crystallographic structure. This might be an indication of a difference in their fluctuation time scales. These observations are discussed in terms of the temperature-driven metal-insulator transition in the $R{\mathrm{NiO}}_{3}$ family.

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.
