Multistep coupling of preexisting local ferroic distortions in PbTiO<sub>3</sub> above the Curie temperature.

Temperature-dependent Raman spectroscopic analyses were performed for the prominent ferroelectric PbTiO&lt;sub&gt;3&lt;/sub&gt; in the temperature range 130-1040 K, focusing particularly on its paraelectric state above the Curie temperature T&lt;sub&gt;C&lt;/sub&gt; ~763 K. The temperature evolution of the anomalous Raman scattering reveals that not only local ferroic distortions persist at temperatures well above T&lt;sub&gt;C&lt;/sub&gt;, but also there is a sequence of different coupling processes preceding the appearance of long-range ferroelectric order at T&lt;sub&gt;C&lt;/sub&gt;. Our results indicate that, similar to relaxor ferroelectrics, the paraelectric phase of PbTiO&lt;sub&gt;3&lt;/sub&gt; can be considered as an ergodic system of local ferroic distortions, which only on average appears to have cubic symmetry.
