                      and Polarized Neutron Reflectivity (PNR) are employed in
                      this study to investigate the structural and magnetic
                      properties of magnetic multilayers deposited onto highly
                      ordered nanosphere arrays. The multilayers, composed of
                      (Co/Pd) multilayers with different numbers of repeats, were
                      deposited using Molecular Beam Epitaxy (MBE) on a flat
                      silicon (Si) substrate and on densely packed two-dimensional
                      arrays of silica nanospheres with diameters of 50 nm and 200
                      nm, formed using an improved drop-casting method [1]. The
                      use of highly ordered nanosphere arrays as substrates
                      introduces a periodic nanostructure that significantly
                      modifies the morphology and magnetic behavior of the
                      multilayers. GISANS provides detailed insights into the
                      lateral structural organization, revealing pronounced
                      periodic ordering influenced by the underlying nanospheres.
                      This lateral order affects the magnetic domain configuration
                      and anisotropy. PNR offers depth profiles, showing increased
                      interfacial roughness and altered magnetic coupling between
                      layers due to the nanosphere-induced topography.The findings
                      demonstrate that highly ordered nanosphere arrays enhance
                      interfacial roughness, alter magnetization reversal
                      processes, and induce spatial variations in magnetic
                      anisotropy, leading to modified magnetic domain structures.
                      These results highlight the potential of using highly
                      ordered nanosphere arrays to engineer magnetic materials
                      with tailored properties for specific applications. This
                      study advances the understanding of magnetism in curved
                      nanostructured systems and paves the way for designing
                      advanced magnetic materials with optimized functionalities.},
