Abstract

The study of dielectric anomalies at structural phase transitions, for many years a standard technique, has only recently been applied to Jahn-Teller (JT) phase transitions. A number of interesting results have already been obtained, some of which will be described below. They include the identification of novel JT behaviour in PrCl3 and some of its isomorphs1–3, and the observation of interesting dielectric anomalies in previously studied JT systems such as DyVO4 4 and CeES5 (ES = ethyl sulphate). For convenience only rare-earth insulating JT systems will be discussed. Many of their properties have been reviewed in lectures by Harley, by Kjems, and by Stinchcombe at this conference, and in an article by Gehring and Gebring6.
