Coupled polarization and nanodomain evolution underpins large electromechanical responses in relaxors. Kim, J., Kumar, A., Qi, Y., Takenaka, H., Ryan, P. J, Meyers, D., Kim, J., Fernandez, A., Tian, Z., Rappe, A. M, LeBeau, J. M, & Martin, L. W Nat. Phys., 18(12):1502–1509, Nature Publishing Group, October, 2022. doi abstract bibtex Understanding the evolution and role of nanoscale polar structures during polarization rotation in relaxor ferroelectrics is a long-standing challenge in materials science and condensed-matter physics. These nanoscale polar structures are characterized by polar nanodomains, which are believed to play a key role in enabling the large susceptibilities of relaxors. Using epitaxial strain, we stabilize the intermediate step during polarization rotation in epitaxial films of a prototypical relaxor and study the co-evolution of polarization and polar nanodomains. Our multimodal approach allows for a detailed examination of correlations between polarization and polar nanodomains; illuminates the effect of local chemistry, strain and electric field on their co-evolution; and reveals the underappreciated role of strain in enabling the large electromechanical coupling in relaxors. As the strain increases, the competition between chemistry-driven disorder and strain-driven order of the polar units intensifies, which is manifested in the coexistence of inclined and elongated polar nanodomains in the intermediate step of polarization rotation. Our findings establish that structural transitions between polar nanodomain configurations underpins the polarization rotation and large electromechanical coupling of relaxors. Properties of relaxor ferroelectrics are governed by polar nanodomains. Polarization rotation facilitated by these domains investigated by means of epitaxial strain reveals a competition between chemistry-driven disorder and strain-driven order.
