30. Although the spin order is not sensitive to the value of α, the exact spin pattern does. This can be best seen from Figs. 9 10, where the relative angles between spins in layer 1 and layer 8 is different at different α.
31. We remark that L. Brey in Ref. also previously reported a charge-ordered CE state at the interface between a FM metal and a large-gap insulator, such as SrTiO3, due to a reduction in the electronic density at that interface.

36. In D. Efremov, J. van den Brink, and D. Khomskii, Nature Mater. 3, 853 (2004) a modified CE state was discussed in the context of ferroelectric states. In this reference, the orientation of the spins within the zigzag chains is modified with respect to the pattern in the perfect CE state via the introduction of dimers. The state of Efremov, does not appear to be the same as in the canted CE state discussed in the present paper but further work is needed to fully address this issue. 10.1038/nmat1236

38. The compensation is not complete when considering the breathing mode in the model. In heterostructures, the periodicity of the lattice distortions along the z direction is lost so that the total volume of the lattice may not be kept constant due to the existence of the breathing mode.

44. In the bulk phase diagrams presented in this paper (Figs. 2 7), we only considered uniform phases that have been confirmed in experiments. However, quasi-2D phases may exist in heterostructures, especially near the interface. In this case, it would be more appropriate to compare with a 2D phase diagram. However, we have found that the 2D phase diagram is qualitatively similar to the three-dimensional (3D) bulk diagram (with the A-AFM phase substituted by an orbital-ordered FM phase). Therefore, only 3D bulk phase diagrams are presented in this paper. It should be noted that given the complexity of the system, even the phase diagram in the bulk limit is not fully clear in the entire parameter space. It would be interesting for future efforts to analyze whether some of the exotic phases in heterostructures may also appear in the bulk phase diagrams in some particular parameter regime.
