Tomasz Jaroń and Wojciech Grochala report the results of electronic band structure calculations for two important fluoroargentates (II): Cs2AgF4 and compressed AgF2. They are able to explain why Cs2AgF4 is an insulating FM and they argue that α-AgF2 (which is a spin-canted FM at 1 bar) should turn into an AFM insulator at 15 GPa (δ-AgF2), which should in turn become metallic or possibly superconducting upon subsequent compression (40 GPa). The AFM ordering makes layered δ-AgF2 the first known analogue of the parent (undoped) compounds of the oxocuprate superconductors. Volume2, Issue2March 2008 RelatedInformation
