Abstract
The piezoelectric switching of antiferroelectric domains by the simultaneous application of an electric field Ei and mechanical stress Tjk is proposed as a direct method for examining whether some spinel compositions do have point symmetry 43m and concomitant antiferroelectric ordering as proposed by Grimes (see abstr. A30773 of 1973). For point symmetry 43m, various possible switching procedures have been described in detail. The smallest coercive product of electric field and stress (EiTjk)c is required for switching when the electric field is chosen along cubic (001), and directional stress along (110) or (110). For particular directions, for example (111), the colinear application of electric field and stress also leads to switching.
