Structural characterization of BMT-134 (BaMn3Ti4O14.25) (a), Synchrotron X-ray powder diffraction and PDF refinement patterns (b), crystal structure of BMT-134 projected down the c-axis and a simple cartoon depiction of how spin and charge distribution in the lattice can cause collective polarization. (c) and (d), the atomic images obtained by spherical-aberration corrected STEM, with the zone axis along [001].
