Abstract :
Two outstanding contributions to the knowledge of ferroelectric materials were made in 1955. A new group of ferroelectric crystals was discovered at Bell Laboratories (187,188), typified by the crystal GASH--guanidine aluminum sulfate hexahydrate. They are characterized by ferroelectricity, but it is at present believed that they show only negligible piezoelectricity. In addition, a firm experimental foundation for the development of a theory of ferroelectricity in perovskites has now been laid by the elucidation of the ferroelectric structures of BaTi03 and PbTiO3 (50,135).
