Abstract
Dielectric measurements have been carried out on the single crystals of DyV, TbV, and TmV through the Jahn-Teller transition temperatures. An anomalous increase of the dielectric susceptibility with temperature along the axis was observed for DyV, but not for TbV and TmV. This behavior is explained as due to the antiferroelectricity driven by the soft strain mode through the "sublattice piezoelectricity."
