      abstract     = {The electronic structure of Fe has been experimentally
                      studied using angle-resolved photoemission spectroscopy
                      (ARPES) since the early days of photoemission. Yet, the
                      existence and nature of the Fe(001) surface state remain a
                      subject of ongoing debate. Fe(001) is considered a
                      prototypical transition metal system and moreover, one of
                      the key players in the spintronics research. Here, we
                      present the electronic structure of Fe(001) epitaxially
                      grown on Au(001), mapped by high-resolution ARPES within the
                      entire surface Brillouin zone, to demonstrate for the first
                      time the exact location and extent of the Fe(001) surface
                      state. The experimental results are supported by the
                      relativistic slab calculations performed using density
                      functional theory (DFT). The surface state observed for the
                      pristine Fe(001) surface vanishes after overnight rest of
                      the sample in ultrahigh vacuum as well as after intentional
                      exposure to 5 Langmuir of oxygen which proves that it is not
                      topologically protected. Furthermore, the dispersion of the
                      surface state is found to depend on the relative orientation
                      of the magnetization, which is explained based on the DFT
                      results as related to the Rashba effect. These new
                      experimental and theoretical results contribute to the
                      existing knowledge on the electronic properties of Fe(001)
                      with relevance for the basic research as well as for
                      spintronic effects, such as tunneling anisotropic
                      magnetoresistance.},
