A combination of both Raman and Brillouin scattering experiments as well as Molecular Dynamics (MD) was used to study the superionic behaviour of BaF2 doped with a wide range of LaF3 concentrations (0 ⩽ x ⩽ 50 mol%). Raman spectroscopy reveals th

High temperature Raman and Brillouin light scattering experiments have been combined with molecular dynamics simulations to provide a comprehensive study of the superionic state of BaF 2 ( x v mol% LaF 3 ) over a particularly wide range of LaF 3 dopa

The local environments of Cd and Pb cations in Cd1-x Pb x F2 as a function of x have been measured by means of extended X-ray absorption fine structure (EXAFS). The compositional dependence of disorder has been studied and reveals that the second she

The local evironments of Cd and Pb cations in the system Cd1−xPbxF2 (x = 0.6) have been measured by means of EXAFS. A comparative analysis of the Fourier transforms of the experimental data provides evidence of the Pb-F bond length being longer tha

The reliability of the lattice simulations depends on the quality of the potentials used. Hence, the interionic potentials of CdF2 were derived and used in the calculations of the crystal bulk data. The temperature dependences of elastic constants is

Mixed-cation superionic fluorites are exceptionally good F- ion conductors due to the mixed nature of the cation sublattice. In this study, we have used extended x-ray absorption fine structure (EXAFS) spectroscopy to gain insights into the local env

We report molecular dynamics and EXFAFS studies of Cd0.4Pb0.6F2 mixed system. A striking feature of molecular dynamics studies in Cd0.4Pb0.6F2 is the mobility of F− ions below. Tc calculations of defect activation energies and plots of single ion t

The squares of the Brillouin frequencies (ΔωB)2 of the LA mode in the [100] direction related to the C11 elastic constant show a linear decrease with temperature followed by significant deviations that occur above the corresponding transition tempe
