研究表明，在具有磁电效应的多铁性晶体中，挠曲电效应的存在可以增加晶体的电极化。锰氧化物基类钙钛矿多铁性材料的极化可以增加，如果在MnO 6八面体的菱面体畸变后形成的菱面体的长轴可以经历扇形空间旋转，导致挠曲电效应。
It has been shown that the electric polarization in multiferroic crystals exhibiting the magnetoelectric effect can be increased in the presence of the flexoelectric effect. The polarization in manganite-based perovskite-like multiferroics can be increased if the long axes of the rhombohedra formed upon the rhombohedral distortion of MnO6 octahedra can undergo fan spatial rotations, leading to the flexoelectric effect.
