Abstract

Anharmonic properties of MgB2

Author(s): P.K.Yadawa, R.R.Yadav

aThe higher order elastic constants have been calculated for hexagonal structured material MgB2 at 300K using Lennard-Jones interaction potential. The orientation dependent three types of acoustic wave velocities and Debye average velocities have been also evaluated using second order elastic constants and related parameters. The behaviour of the orientation dependent acoustic wave velocities of this material has been discussed.
