Abstract

The mechanisms of the onset of the piezoelectric effect in configurations that do not allow the occurrence of the piezoelectric response in the paramagnetic state by the symmetry have been investigated. In this paper, in contrast to the symmetry constraints, the existence of such a piezoelectric response was detected. It is assumed that the response is due to the surface on which no symmetry restrictions. In the magnetically ordered state in these configurations, the indirect piezoelectric effect consisting in the joint action of the magnetoelectric and magnetoelastic mechanisms symmetrically admitted and really observed.
