In the present work, we propose to take into account the fact that perovskites with mixed conductivity, as a rule, belong to the ferroics, namely to ferroelastics, which in turn allows us to use models and ideas developed for the related class of ferroics-ferroelectrics. Nanostructuring due to the formation of twins is characteristic for both kinds of materials. This approach allows us to develop a theoretical base for the strategy of doping MIEC perovskites by ferroactive cations, proposed in early; it is actively used at present to achieve purposeful regulation of the functional properties of nanostructured MIEC perovskites, which are promising as electrode materials for SOFCs.
