抄録

Based on the Full potential linearized augmented plane wave (FLAPW) method, the electronic properties of incommensurate anti-ferromagnetic Sr₄V₂O₆Fe₂As₂ with wave vector q = (0, 0, 0.306) have been investigated. Comparing total energy between those of non-magnetic and incommensurate anti-ferromagnetic states (i-AF) we suggest that the i-AF is the stable configuration in this superconductor. The density of states data exhibit strong spin-polarized effect on the V site and possible hybridization between V-3d and Fe-3d orbitals. We found as many as six bands crossing the Fermi level, indicating strong inter-band scattering. The analysis of Fermi surfaces reveals a multi-sheet character, which is compiled of several hole-type cylinders around the center and electron-type sheets at the corners of the Brillouin zone.
