  1. Four adsorption registries have been considered: Hollow, Bridge, Top-B, Top-N. d (in Å) is the MBT-hBN interlayer distance (see Fig. 2(a)), EAFM and EFM (in meV) are the energies of the respective interlayer magnetic states relative to that of the AFM-hollow case (whose energy is set to zero), ΔEA/F = EAFM − EFM (in meV per Mn pair) is the total energy difference of the interlayer AFM and FM states, Sxy is the anomalous Hall conductance for the Fermi level lying within the fundamental band gap, and C is the Chern number obtained for the interlayer FM state in MBT2SL.
