      abstract     = {The coexistence of different order parameters can lead to
                      exotic new quantum phenomena. In hardcondensed matter
                      materials, their interplay often generates magnetic chiral
                      structures with correlationson the nanometer and mesoscopic
                      length scale, which can be explored by
                      polarization-analyzedSmall-Angle-Neutron-Scattering (SANS)
                      in bulk systems, and by its surface-sensitive
                      counterpartGrazing-Incidence-SANS (GISANS) in thin film
                      structures. Thin film Nb/FePd exhibits
                      coexistingsuperconducting and ferromagnetic phases,
                      affecting both the superconducting and the magneticorder
                      around its superconducting Tc [1,2]. While around Tc in Nb
                      the superconducting state is confinedabove the domain walls
                      of FePd, the superconducting state itself is affecting the
                      width wDWof magnetic domain walls in FePd [1].Although a
                      Dzyaloshinskii–Moriya Interaction (DMI) leading to
                      magnetic chirality is not expectedin the L10-structured
                      FePd, its domain walls obtain a preferred chiral direction,
                      unveiled by polarizedGISANS. An extensive study combining
                      GISANS, circular-dichroism X-ray Resonant MagneticScattering
                      (CD-XRMS), and Density Functional Theory (DFT), yields
                      unique insight into the chiralwall formation and its
                      origin.At the ESS, neutron polarization analysis will be
                      supported on many instruments [3], and togetherwith a wide
                      range of sample environments will enable pioneering science
                      projects. Based on theabove-mentioned science case using
                      polarized GISANS, I will additionally present the impact
                      frominstrumentational and data reduction aspects.[1] A.
