Extraordinary pressure dependence of the metal-to-insulator transition in the charge-transfer compounds NdNiO3and PrNiO3
Abstract
The pressure dependence of the metal-to-insulator transition in NdNiO${}_{3}$ and PrNiO${}_{3}$ has been studied up to applied hydrostatic pressures of 16 kbar. In both cases the first-order metal-to-insulator phase transition is extremely sensitive to pressure, with 15.1 kbar suppressing the transition from 196 to 103 K in NdNiO${}_{3}$ and 14.1 kbar suppressing the transition from 130 to below 1.5 K in PrNiO${}_{3}$. Analysis of the data within the framework of charge-transfer gap insulators leads to the prediction that the primary effect of pressure is to straighten the Ni-O-Ni bond angle, leading to a broadening of the lower, oxygenlike valence band.

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.
