Pressure Dependency Grüneisen Parameter r for bcc Mo

Abstract

It has been reinforced by Kushwah et al. (Kushwah, 2013) that the Lindemann law doesn't work satisfactorily for the transition metals. We think this point is open to question. Combining the Lindemann law and the Vinet et al thermal equation of state with the melting curves of bcc Mo, we present an explicitly simple expression of the pressure dependency Grüneisen parameter γ for Molybdenum. The results yield good agreement with density functional theory and experiments.
