Abstract

We have investigated the lattice vibrational properties of the rare-earth (RE) Yb-pnictide compounds by using a three-body force rigid-ion model suitable for these compounds. The calculated phonon-dispersion curves (PDC) reveal that these compounds do not show any anomaly in their phonon properties, particularly in view of their recently measured elastic and optical properties, such as shown by other RE compounds having NaCl structure. We emphasize the need of measurements of the complete PDC of Yb-pnictide compounds to support the recent results on elastic, optic, and the presently calculated phonon properties.
