Dielectric Constant in Perovskite Type Crystals
Abstract
Slater's theory of the dielectric constant in BaTi${\mathrm{O}}_{3}$ has been extended by treating the ionic polarizability quantum mechanically instead of classically. This leads to an expression for the dielectric constant which is good at all temperatures and shows a deviation from the Curie-Weiss law at low temperatures. The theory is applied to SrTi${\mathrm{O}}_{3}$ and to KTa${\mathrm{O}}_{3}$ above its transition at 13.2\ifmmode^\circ\else\textdegree\fi{}K.

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.
