In this paper, we evaluate the fitting parameters for the hopping model for the $d_{xy}$ and $d_{xz}$ bands within the $\Gamma$–M cut for different FeSe-based superconductors. Comparison of these parameters for DFT calculations and for experimentally obtained data reveals a dramatic change of hopping probability between the nearest neighbours. This change is much bigger than the expected band renormalization and can be explained by the appearance of an antiferromagnetic-like ordering.

Key words: FeSe, electronic structure, iron-based superconductors, intercalated systems, FeSe films.
