Electronic Structure Studies of CeAgSb2

The electronic band structure of CeAgSb$_{2}$ has been calculated using the self-consistent full potential nonorthogonal local orbital minimum basis scheme based on the density functional theory. We investigated the electronic structure with the spin-orbit interaction and on-site Coulomb potential for the Ce-derived 4f orbitals to obtain the correctly ground state of CeAgSb$_{2}$.
