Abstract

The temperature dependence of the elastic properties of antiferroelectric PbHfO 3 was investigated by using Brillouin scattering. The two structural phase transitions of antiferroelectricantiferroelectric-paraelectric phases were clearly identified from the discontinuous changes in the acoustic mode frequencies and the hypersonic damping. The substantial softening of the mode frequency, along with the remarkable increase in the acoustic damping observed in the paraelectric phase, indicated the formation of precursor noncentrosymmetric (polar) clusters and their coupling to the acoustic waves. This was corroborated by the observation of quasi-elastic central peaks, the intensity of which grew upon cooling toward the Curie point. The obtained relaxation time exhibited a slowing-down behavior, suggesting that the dynamics of the precursor clusters became more sluggish on approaching the phase transition temperature.

  • The maximum permittivity falls between the temperatures of the two transitions observed in bulk PHO around 160 °C and 210 °C.

    From The other model antiferroelectric: PbHfO3 thin films from ALD precursors (2021) · cites this paper as [36]

    The Introduction (p. 3) places PbHfO3’s two phase transitions at approximately 160 °C and 210 °C. The paper examines elastic properties, however, and the passages on the transitions (Results and Discussion, p. 5) do not establish that the permittivity reaches its maximum between them; searches for a permittivity or dielectric maximum found no such passage.

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.
