Figure 2
Structure factor of polarized BaTiO3. (a) Argand diagram for the Friedel pair of reflections. The sum of contributions from non-resonant atoms is denoted [{\tilde F}_h]. The anomalously scattering atom contributes with an atomic scattering factor, including the dispersion corrections. The relative phase between the contribution from this atom and all the other atoms is denoted ψ. (b) The tetragonal unit cell of polarized BaTiO3. The arrow illustrates that polarization emerges due to the displacement of the Ti4+ ion along the [001] direction.
