Abstract

The effects of spin structures on the Fermi surface topologies of BaFe 2As2 were calculated using the first-principles approach. Here, we considered the nonmagnetic, Checkerboard, Stripe, and SDW (spin-density-wave) structures as well as a tetragonal structure labeled as STR17. By comparing the calculated results with the published angle-resolved photoemission spectroscopy from the literature, we propose that most of the experimentally observed Fermi surfaces of BaFe2As2 are the thermal mixture of those of the SDW, STR17, and Stripe structures.
