Band Structure of LaSrGaO4 and LaSrAlO4 Compounds

The band structures of the ordered LaSrGaO 4 (LSG) and LaSrAlO 4 (LSA) compounds are calculated by the TB LMTO-ASA method. The spin-orbit interaction was included in the valence electrons. We observe gaps (0.17 Ry for LSA and 0.15 Ry for LSG) at the Γ point for both systems.

Electronic Structure of Hf1−xZrxV2 Alloys

The electronic structure of the pseudobinary cubic Laves phase (C15) Hf 1-x Zr x V 2 alloys is presented. The self-consistent band calculations are made by the tight-binding LMTO method. The calculated density of states at the Fermi level reaches a maximum at x = 0.35. The experiments indicated that the electronic specific heat coefficient and the susceptibility have a maximum at the same concentration of zirconium.
