“…These compounds have ionic conductivities at temperatures well below the melting temperature which finds potential application as solid state electrolytes. From the experimental side several interesting properties of alkaline-earth halides such as electronic structure and optical spectra, elastic constants, lattice dynamics and high-pressure structural phase transitions have been studied [2][3][4][5][6][7][8][9]. From the theoretical point of view the electronic structure, structural phase stability, equation of state, elastic constants, ionic conductivity, and temperature dependence of elastic parameters have been determined [10][11][12][13][14][15][16][17][18][19].…”
