• 論文の詳細を見る

• A microscopic calculation is carried out for thermal properties of ionic crystals onthe basis of the thermodynamic variational principle. Self-consistent Einstein approximation is used to obtain effective force constants between constituent ions. Thermalexpansion, temperature dependencies of the elastic constants and dielectric constantsof tonic crystals are evaluated itt terms of interatornic potentials. The results ofnumerical calculations for alkali halide crystals are in good agreement with experimental data.[thermal properties, tonic crystals, lattice dynamics, theory, thermal expansion, ll elastic constants, dielectric cortstants, alkali halidel
