Spin response in LiFeAs and NaFeAs iron-pnictides superconductors — •Felix Lochner, Felix Ahn, and Ilya Eremin — Ruhr-Universität Bochum, Bochum, Deutschland

We analyze the spin susceptibility in LiFeAs and NaFeAs by using the ten-orbital tight-binding model that we fitted to the electronic band structure measured by recent ARPES experiments. We identify an effective five-band model for a weak kz-dependence. Besides we present the bare and RPA-susceptibility and its qz dependencies to study the magnetic instabilities and estimate the strength of intra-orbital and inter-orbital nesting.
