      abstract     = {We present a systematic first-principles study of the
                      electronic surface states and resonances occuring in thin
                      films of Pd of various thicknesses deposited on a single
                      ferromagnetic monolayer (ML) of Fe on top of Ir(111)
                      substrate. This system is of interest since one Pd layer
                      deposited on Fe/Ir(111) hosts small magnetic skyrmions. The
                      latter are topological magnetic objects with swirling
                      spin-textures with possible implications in the context of
                      spintronic devices since they have the potential to be used
                      as magnetic bits for information technology. The
                      stabilization, detection and manipulation of such
                      non-collinear magnetic entities require a quantitative
                      investigation and a fundamental understanding of their
                      electronic structure. Here we investigate the nature of the
                      unoccupied electronic states in Pd/Fe/Ir(111), which are
                      essential in the large spin-mixing magnetoresistance
                      signature captured using non spin-polarized scanning
                      tunneling microscopy (Crum et al 2015 Nat. Commun. 6 8541,
                      Hanneken et al 2015 Nat. Nanotechnol. 10 1039). To provide a
                      complete analysis, we investigate bare Fe/Ir(111) and Pd n =
                      2,7/Fe/Ir(111) surfaces. Our results demonstrate the
                      emergence of surface and interface states after deposition
                      of Pd MLs, which are strongly impacted by the large
                      spin–orbit coupling of Ir surface.},
