Induced Flexoeffect in Materials with Anisotropic Atomic Groups

Abstract
The possibility of flexoelectric effect in the applied electric field is discussed when there are rhombohedral distortions of octahedrons in materials with anisotropic atomic groups which consist of various atoms allowing long axes of forming octahedrons to do harp turnings in space. Such a flexoeffect is characterized by formation of periodic structure, it has threshold character and depends on mechanical compliance of octahedrons and results in certain increase in the homogeneous electrical polarization of a material.
