Important experimental findings and their impact on physical properties of Ni thin film are presented with the focus on structural and magnetic property investigations. For this purpose, Ni film (40 nm) was deposited on polystyrene nanospheres (PS, diameter 800 nm) using electron beam evaporation technique simultaneously with a similar reference film on plane Si substrate. The structural properties of the films measured using XRD technique show nanocrystalline growth of Ni on both size PS spheres with an average grain size of ∼ 78 nm, while high crystallinity was observed in the film deposited onto plane Si substrate. A lower coercivity (9 mT) was observed in the Ni/(800 nm) PS as compared to the film deposited on 530 nm PS (23 mT) (our earlier study) and Ni/Si (20 mT). The observed changes in structural and magnetic properties are attributed to the curvature induced modifications at atomic level.
