      abstract     = {Both, the Rashba effect and the Dzyaloshinskii-Moriya
                      interaction (DMI) rely on inversion symmetry breaking and
                      spin-orbit coupling (SOC) effects. While the qualitative
                      behavior of both is easily described on a model level,
                      quantitative insights in strength and sign are not so easy
                      to obtain. Density functional theory (DFT) offers an
                      effective tool to study these effects on an ab initio level.
                      E.g. it was found that oxygen coverage changes both, the
                      sign of the Rashba constant on a metal surface [1], and that
                      of the DMI in a magnetic thin film [2]. We shortly discuss
                      the interplay of magnetism and the Rashba effect and
                      questions about the size and sign of the Rashba constant.
                      These findings will be connected to recent models on
                      so-called Rashba- and SOC-mediated DMI. DFT calculations of
                      simple trilayer systems based on a Co/Pt interface show that
                      the DMI can not only vary by a factor of 2−3, but also
                      change sign depending on the inclusion of a third element
                      [3]. We acknowledge discussions and collaborations with H.
