Multiferroics constitute the group of materials for which a remarkable upsurge in their electrical and magnetic properties occurs for specific 'MPB'-compositions. Consequently, multiferroics and their peak electrical and magnetic performance are intensely nowadays investigated.
Our atomistic calculations suggest that monitoring of mechanical characteristics of these materials might be helpful in tuning them to their top performance, without changing their composition. We also stipulate the possibility of structure control by localized stress as an alternative to composition-governed behavior. Indeed, our experiments demonstrated the properties alteration achieved by nanodeformation of multiferroics fabricated by the sol-gel method. Thus we explored the possibility of inducing phase changes that result in a superior blend of material characteristics. The observed phenomena have significant potential for the indentation lithography and may result in a design of stress-steered devices.
