Abstract

The electronic structure and the structural stability of the trialuminides YAl3, ZrAl3, and NbAl3 in the cubic L12 and tetragonal D022 structures were investigated by means of the total-energy all-electron self-consistent linear muffin-tin orbitals (LMTO) method. The variation of the stability across the constituent transition-metal series can be understood simply in terms of the band filling of the bonding states. And surprisingly, the simple rigid-band approximation appears adequate to describe the structural stability of these (p-d covalent) trialuminides.
