We aim at understanding the proximity effects in the superconductor-ferromagnet (S/F) interface of Nb(S)/FePd(F) thin film heterostructures, prepared by MBE growth. Proximity effects at S/F interfaces with an inhomogeneous magnetic field texture result in various effects, like domain-wall superconductivity. To reveal the physical origin of each effect, we compare samples with S/F in direct proximity and S/F decoupled by a thin MgO layer. Measurements of the resistivity and magnetization show striking differences in their critical temperature and the critical field values. According to our results, we ascribe the observed domain-wall and reverse-domain superconductivity to the long-range magnetic interactions. Using polarized neutron scattering techniques, we focus on revealing the lateral magnetic depth profile of the heterostructures as function of temperature.
