Figure 3
Schematic model for the in-plane orientation of Fe3O4(111) grown on SrTiO3(001). The larger green circles denote the Sr2+ cations and the smaller red circles represent the Fe3+ cations of the Fe3O4(111) unit cell. For simplicity, Ti and O atoms are not shown and the surface unit cell of Fe3O4(111) is used. The two possible domains, A and B, rotated by 90°, are shown. [Adapted from Leung et al. (2008 |
