Title: Spin-Orbit Interactions and the Nematicity Observed in the Fe-Based Superconductors

Abstract

High-resolution angle-resolved photoelectron spectroscopy is used herein to examine the electronic band structure of FeTe 0.5 Se 0.5 near the Brillouin zone center. A consistent separation of the α 1 and α 2 bands is observed with little k z dependence of the α 1 band. First-principles calculations for bulk and thin films demonstrate that the antiferromagnetic coupling between the Fe atoms and hybridization-induced spin-orbit effects lifts the degeneracy of the Fe d x z and d y z orbitals at the zone center leading to orbital ordering. These experimental and computational results provide a natural microscopic basis for the nematicity observed in the Fe-based superconductors.
