Comments on the formation entropy of a Frenkel defect in BaF2 and CaF2
Abstract
The entropy for the formation of a Frenkel defect in alkaline-earth halides has been estimated using the defect's formation enthalpy and the temperature variation of the crystal's bulk modulus. The values obtained for BaF2 and CaF2 are in good agreement with the experimental results.
