      abstract     = {A key element to tailor the properties of magnetic
                      multilayers is the coupling between the individual magnetic
                      layers. In the case of skyrmion hosting multilayers,
                      coupling of skyrmions across the magnetic layers is highly
                      desirable. Here, the magnetic interlayer coupling was
                      studied in epitaxial all-oxide heterostructures of
                      ferromagnetic perovskite SrRuO3 layers separated by spacers
                      of the strong spin–orbit coupling oxide SrIrO3. This
                      combination of oxide layers is being discussed as a
                      potential candidate system to host Néel skyrmions. First
                      order reversal curve (FORC) measurements were performed in
                      order to distinguish between magnetic switching processes of
                      the individual layers and to disentangle the signal of soft
                      magnetic impurities from the sample signal. Additionally,
                      FORC investigations enabled us to determine whether the
                      coupling between the magnetic layers is ferromagnetic or
                      antiferromagnetic. The observed interlayer coupling strength
                      was very weak for the heterostructure with a two monolayer
                      (ML) thick SrIrO3 spacer, and no coupling was observed for
                      spacers of 6 and 12 ML thickness. The decoupling of the
                      magnetic SrRuO3 layers due to the SrIrO3 spacer is a
                      disadvantage for the study of skyrmions in such multilayers
                      and indicates that other oxides have to be identified for
                      realizing strong magnetic coupling},
