      abstract     = {Sandwich-molecular wires consisting of europium and
                      cyclooctatetraene (Cot) were grown in situ on the moiré of
                      graphene with Ir(110). The moiré templates a uniaxial
                      alignment of monolayer EuCot nanowire carpets and multilayer
                      films with the EuCot wire axis along the [001] direction of
                      the Ir substrate. Using angle-resolved photoemission
                      spectroscopy, we investigate the band structure of the wire
                      carpet films. While π-derived bands were not observed
                      experimentally, we find a flat band 1.85 eV below the Fermi
                      energy. Using density-functional theory and X-ray
                      photoelectron spectroscopy and replacing europium through
                      barium in the sandwich-molecular wires, it is concluded that
                      the flat band is derived from Eu 4f states weakly mixed with
                      Eu 5d states and slightly overlapping with Cot π states.
                      X-ray magnetic circular dichroism is employed to
                      characterize the magnetic properties of the EuCot wire
                      carpet films at low temperatures. Clear evidence for an
                      easy-axis magnetization along the wires is found.},
