Dielectric anomaly and improper antiferroelectricity at the Jahn--Teller transitions in rare-earth vanadates
Description
Dielectric measurements have been carried out on the single crystals of DyVO4, TbVO4, and TmVO4 through the Jahn--Teller transition temperatures. An anomalous increase of the dielectric susceptibility with temperature along the c axis was observed for DyVO4, but not for TbVO4 and TmVO4. This behavior is explained as due to the antiferroelectricity driven by the soft B/sub 1g/ strain mode through the ''sublattice piezoelectricity.''
