      abstract     = {Proximity effects in superconductor/ferromagnet thin film
                      heterostructures are ahighly topical issue due to their
                      potential application in superconducting spin valvesor
                      fluxonic devices [1, 2]. Physical properties can be
                      controlled by an appliedmagnetic field and emerge for
                      example as stray-field generated domainsuperconductivityor
                      spin-triplet correlations. Our goal is to investigate their
                      interplayand tunability by an external magnetic field. We
                      use a heterostructure system ofNb/FePd with varying strength
                      of magnetocrystalline anisotropy and a lateral
                      domainstructure, grown by molecular beam epitaxy.On the one
                      hand, macroscopic magnetoelectric transport measurements
                      reveal aconfined superconducting state due to the stray
                      fields of L10-ordered FePd. On theother hand, direct
                      proximity effects at the Nb/FePd interface with a
                      non-collinearmagnetization presumably lead to the generation
                      of spin-triplet Cooper paircomponents with long penetration
                      depth within the ferromagnetic layer [3].

                      onset of domain-wall-superconductivity. This mechanismcannot
                      be revealed by macroscopic magnetization measurements, which
