摘要：

Dielectric studies are presented of a banana-shaped compound that exhibits the antiferro-electric B-2 phase. Upon application and subsequent removal of strong electric fields the textures and dielectric properties of the phase drastically change. Most notable is the huge increase of the low frequency permittivity. This behaviour would suggest the induction of ferroelectricity by the electric field.
