Three-Dimensional Pseudo-Ferroelectric Domain Walls in BiFeO <sub>3</sub> : Atomic-Scale Oxygen Octahedral Rotation and Polar Geometry
]. These noncanonical 3D walls arise from oxygen-rearrangement-induced structural deviations and asymmetric Fe-O lattice coupling, which generate chiral polarization stabilized by a potent tripartite interaction between ferroelectric, shear, and spin degrees of freedom. This work provides a design principle for reconfigurable domain wall nanoelectronics.
