AN ESTIMATION OF ELECTRONIC CONTRIBUTION TO THE DEBYE TEMPERATURE OF TRANSITION-METALS

The electronic contribution to the Debye temperature of transition met als is calculated using the Wills-Harrison model for representing the effective interatomic interaction. For bcc metals, interactions prevai ling up to the second coordination shell are taken into account. The c alculated Debye temperatures are found to be in reasonable agreement w ith the available empirical and non-empirical estimates. The periodic variation of Debye temperature is attributed to the role of d-band eff ects in controlling crystal cohesion.
