Table 1 Structural properties and energetics for bulk and surface (with and without RuO6 tilts) Sr3Ru2O7 systems. Θ and Φ (°) indicate tilts and rotations as described in Fig. 1c. RuX-O distances (Å) are distances between in-plane Ru and O atoms as seen in Fig. 1a. Total energy differences between FM and lowest energetically AFM phases (ΔE = E AFM −E FM per formula unit in meV). Stronger FM character is observed at the surface in comparison to the bulk.
