Investigation of magnetic phases in parent compounds of Iron-chalcogenides via quasiparticle scattering interference

Abstract

We employ a five-orbital tight-binding model to develop the mean field solution for various possible spin density wave states in the iron-chalcogenides. The quasiparticle interference (QPI) technique is applied to detect signatures of these states due to scatterings arising from non-magnetic impurities. Apart from the experimentally observed double striped structure with ordering vector $(\pi /2,\pi /2)$, the QPI method is investigated for the extended-stripe as well as the orthogonal double stripe phase. We discuss QPI as a possible tool to detect and classify various magnetic structures with different electronic structure reconstruction within framework of the Fe${}_{1+y}$Te compound.
