      abstract     = {Three direct proximity effects in
                      ferromagnet-superconducting thin film heterostructures of Nb
                      andFePd with a lateral domain pattern have been found by
                      temperature dependent electrical resistivitymeasurements,
                      showing the influence of the magnetic domain structure on
                      the superconductingstate: reversed domain superconductivity,
                      domain wall superconductivity and generation of
                      spintripletCooper pairs [1].In this system, the inverse
                      proximity effect, i.e. the effect of the entrance in the
                      superconducting stateon the magnetic structure has been
                      studied by temperature dependent grazing incidence small
                      angleneutron scattering (GISANS) on the KWS-3 diffractometer
                      at the Heinz Maier-Leibnitz Zentrum [2]and by GISANS with
                      polarization analysis on vSANS at the NIST Center for
                      Neutron Research [3,4].Guided by micromagnetic simulations
                      [5], we present in this contribution simulations of the
                      GISANSdata within the distorted wave Born approximation
                      [6,7]. We find that the domain walls width inFePd with
                      strong perpendicular magnetic anisotropy increases when Nb
                      enters the superconductingstate [8].[1] A. Stellhorn et al.,
