Claims

C1strongest claim

replacing centrosymmetric pyrazine (pyz) ligands with non-centrosymmetric imidazole (imz) linkers in Cr-based MOFs reduces lattice symmetry, enabling g-wave AM spin splitting up to 65 meV. Furthermore, frontier molecular orbital engineering (FMOE) allows selective ligand spin polarization, inducing a shift to d-wave AM anisotropy in polycyclic ligand-based 2D MOFs with spin splitting up to 83.9 meV.

C2weakest assumption

The proposed 2D MOF structures are chemically stable and experimentally synthesizable, and standard DFT approximations accurately capture the magnetic exchange and spin-splitting energies without significant errors from functional choice or missing correlations.

C3one line summary

Ligand replacement and frontier orbital engineering in 2D Cr-MOFs induce g-wave and d-wave altermagnetic spin splitting up to 83.9 meV via DFT, with ligand-mediated exchange stabilizing the order.
