Many-body effects on the third-order elastic constants of alkaline earth fluorides

  • 1. Indian Inst. of Tech., New Delhi. Dept. of Physics

Description

Expressions for the third-order elastic (TOE) constants are derived from the Lundquist potential for the non-centrosymmetric solids crystallizing in the fluorite structure. The values of the TOE constants determined from these expressions agree fairly well with the measured values for CaF2, SrF2, and BaF2 and show significant improvements over the values obtained in other theoretical studies.
