Phase transitions and amorphization of M2AgF4 (M = Na, K, Rb) compounds at high pressure
Jakub Gawraczynski, Łukasz Wolanski, Adam Grzelak +3
We report the results of Raman spectroscopy high-pressure studies of alkali metal fluoroargentates (M2AgF4, where M=Na, K, Rb) associated with theoretical and x-ray diffraction stu…
Crystal structure, lattice dynamics and superexchange in MAgF3 1D antiferromagnets (M = K, Rb, Cs) and Rb3Ag2F7 Ruddlesden-Popper phase
Kacper Koteras, Jakub Gawraczynski, Gasper Tavcar +2
With the use of lattice dynamics calculation within hybrid HSE06 framework we were able to understand vibrational spectra of MAgF3 M = K, Rb, Cs compounds. Comparative theoretical…
Observation of a new polyhalide phase in Ag-Cl system at high pressure
Adam Grzelak, Jakub Gawraczynnski, Mariana Derzsi +3
In this short contribution, we examine Raman spectroscopic data from high-pressure and high-temperature experiments with Ag-Cl system, and find that they are in good agreement…
Lattice dynamics of KAgF3 perovskite, unique 1D antiferromagnet
Kacper Koteras, Jakub Gawraczynski, Mariana Derzsi +2
Theoretical DFT calculations using GGA+U and HSE06 frameworks enabled vibrational mode assignment and partial (atomic) phonon DOS determination in KAgF3 perovskite, a low-dimension…
