Abstract: The use of curved surfaces as substrates for thin film deposition induces lateralvariation in film thickness, which allows variation in the deposited materialproperties. [Co/Pd]n multilayers with differen Co thicknesses were depositedon a flat silicon substrate, and densely packed two-dimensional arrays of silicananospheres with different radii of curvature formed by improved drop-castingmethod [1]. Scanning electron microscopy, X-ray reflectivity (XRR), grazing incidencesmall angle X-ray scattering, SQUID and neutron reflectivity were usedto characterise the obtained nanostructure. Compared to the flat multilayer, thecap multilayer shows a different anisotropy axis direction. A change in coercivityas a function of film thickness and radius of curvature is also observed.[1] A.Qdemat, et.al., RSC Adv., 10, 2020
