      abstract     = {The magnetic structure of a Cr monolayer on a W(110)
                      substrate is investigated by means of first-principles
                      calculations based on noncollinear spin density functional
                      theory (DFT). As magnetic ground state we find a long-period
                      homochiral left-rotating spin spiral on top of an
                      atomic-scale antiferromagnetic order of nearest-neighbor
                      atoms. The rotation angle of the magnetic moment changes
                      inhomogeneously from atom to atom across the spiral. We
                      predict a propagation direction along the crystallographic
                      [001] direction with a period length of |λ|=14.3nm, which
                      is in excellent agreement with a modulation of the local
                      antiferromagnetic contrast observed in spin-polarized
                      scanning tunneling microscope experiments by Santos et al.
                      [New J. Phys. 10, 013005 (2008)]. We identify the
                      Dzyaloshinskii-Moriya interaction as the origin of the
                      homochiral magnetic structure, competing with the
                      Heisenberg-type exchange interaction and magnetocrystalline
                      anisotropy energy. From DFT calculations we extract
                      parameters for a micromagnetic model and thereby determine a
                      considerable inhomogeneity of the spin spiral, increasing
                      the period length by $6\%$ compared to homogeneous spin
                      spirals. The results are compared to the behavior of a Mn
                      and Fe monolayer and Fe double layer on a W(110) substrate.},
