abstract = {Grazing Incidence Small Angle Neutron Scattering (GISANS)
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.},
