      abstract     = {We have investigated the influence of curvature on the
                      magnetic properties of a Co-Pd alloy bydepositing Co-Pd
                      alloy films, with different thicknesses, on monolayers of
                      silicon dioxide (SiO₂)nanospheres, and on flat silicon
                      substrates. The curved films exhibit enhanced magnetic
                      scatteringlength density (mSLD), particularly for the
                      thinner films, compared to the flat substrates. This
                      isattributed to curvature induced strain and orbital
                      hybridization, which boosts the local magneticmoment.
                      However, as film thickness increases, the structural order
                      of the nanosphere monolayersis disrupted, leading to rougher
                      morphology and eventual coalescence into continuous films.
                      SQUIDmagnetometry reveals that curvature alters magnetic
                      anisotropy by weakening or tilting perpendicularmagnetic
                      anisotropy (PMA) and increasing coercivity. Polarized
                      neutron reflectometry (PNR)confirms stronger in-plane
                      magnetization in curved films, and shows that thinner films
                      exhibit ahigher magnetic scattering length density (mSLD)
                      than thicker ones, due to enhanced interface effectsin the
                      ultrathin regime. Despite high structural ordering,
                      grazing-incidence small-angle neutronscattering (GISANS)
                      detects no lateral magnetic coherence or domain-related
                      scattering. Thisstudy highlights the significant role of
                      curvature in tuning the magnetic properties of CoPd
                      alloyfilms and underscores the combined power of PNR and
                      GISANS in probing magnetism in such systems.},
