Changes in lattice strain and symmetry in BiFeO3 (BFO) crystals at coherent T-BFO/LaAlO3 (LAO) and rhombohedral-BFO/LAO interfaces are imaged with atomic resolution using annular bright-field scanning transmission electron microscopy and first-principles calculations. A common pinned BFO layer and polarization relaxation at the interfaces are identified, providing insight into the ferroelectric behavior of thin films and the complex oxide heterointerfaces between them.
