Abstract:
We show, using Density Functional Theory (DFT) calculations, that compressed AgF2 should turn above 17 GPa into a layered narrow‐gap material with a huge intralayer antiferromagnetic (AFM) coupling constant, reminiscent of those seen for parent copper (II) oxides (e.g., La2CuO4). Compressed AgF2 is thus the first candidate for the non‐oxocuprate two‐dimensional antiferromagnet. Calculations indicate that AgF2 could subsequently be metallised above 38 GPa, likely giving rise to superconductivity (SC).
