The parent compound of high-T c superconducting cuprates is a unique Mott insulator
consisting of layers of spin-1 2 ions forming a square lattice and with a record high in-plane …

The silver‐fluorine phase diagram has been scrutinized as a function of external pressure
using theoretical methods. Our results indicate that two novel stoichiometries containing Ag+ …

Ab initio calculations of Ag-based fluoroperovskite AgMF 3 (M= Co and Ni) compounds are
investigated using the full-potential linearized augmented plane wave method. Wien2k and …

The relative stability of various phases of five AVF3 compounds (A= Li, Na, K, Rb and Cs) is
investigated starting from the cubic (C) Pmm (221) prototype structure, with five atoms (one …

The opposing effects of high pressure (in the GPa range) and the Jahn-Teller distortion led
to many intriguing phenomena which are still not well understood. Here we report a …

In this personal account, the author takes readers on the journey to “Silverland,” ie, the
emerging field of electronic and magnetic materials based on divalent silver (Ag 2+). He …

Insulating CuF2 is considered a prototype compound displaying a Jahn–Teller effect (JTE)
which gives rise to elongated CuF64–units. By means of first-principles calculations together …

Studying the effect of high pressure (exceeding 10 kbar) on the structure of solids allows us
to gain deeper insight into the mechanism governing crystal structure stability. Here, we …

The crystal structure, magnetic properties, heat capacity, and Raman spectra of double-
perovskite M2AgF4 (M= K, K3/4Rb1/4, K1/2Rb1/2, K1/4Rb3/4, and Rb) phases have been …

We report the results of high-pressure Raman spectroscopy studies of alkali metal
fluoroargentates (M2AgF4, where M= Na, K, Rb) combined with theoretical and X-ray …
