(color online) (a) Map of the off-center displacements of Fe atom positions in domains D2 (green arrows) and D3 (blue arrows) and in the domain wall area DW3 (red arrows in blue area) projected onto the {110} plane. (b) Map of the magnitude of the oxygen octahedron rotation angle, α, projected into the {110} plane. The area of DW3 is indicated by a white dotted line. A color scale denotes the tilting angles of oxygen octahedra and the magnitude of magnetization.^[30]
