Electric-Field-Induced Domain Switching and Domain Texture Relaxations in Bulk Bismuth Ferrite
Abstract
Bismuth ferrite, BiFeO<sub>3</sub>, is an important multiferroic material that has attracted remarkable attention for potential applications in functional devices. While thin films of BiFeO<sub>3</sub> are attractive for applications in nanoelectronics, bulk polycrystalline BiFeO<sub>3</sub> has great potential as a lead-free and/or high-temperature actuator material. However, the actuation mechanisms in bulk BiFeO<sub>3</sub> are still to be resolved. Here we report the microscopic origin of electric-field-induced strain in bulk BiFeO<sub>3</sub> ceramic by means of in situ high-energy X-ray diffraction. Quantification of intrinsic lattice strain and extrinsic domain switching strain from diffraction data showed that the strain response in rhombohedral bulk BiFeO<sub>3</sub>is primarily due to non-180° ferroelectric domain switching, with no observable change in the phase symmetry, up to the maximum field used in the study. The origin of strain thus differs from the strain mechanism previously shown in thin film BiFeO<sub>3</sub>, which gives a similar strain/field ratio as rhombohedral bulk BiFeO<sub>3</sub>. A strong post-poling relaxation of switched non-180° ferroelectric domains has been observed and hypothesized to be due to intergranular residual stresses with a possible contribution from the conductive nature of the domain walls in BiFeO<sub>3</sub> ceramics.
