In this work, a detailed insitu μGISAXS investigation of the growth of metallic thin films on self-organized nanopatterned templates prepared by low energy ion beam erosion has been done. GISAXS experiments were performed at the P03/MiNaXS beamline of the PETRA III storage ring at DESY (Hamburg, Germany).Two different kind of nanopatterned templates, (i) GaSb nanocones and (ii) nanorippled Si prepared by low energy ion beam erosion under two different experimental geometry have been used as templates to grow thin films of Py and Ag separately. Different growth regimes have been analyzed with increasing thickness. Obtained structural information have been correlated with observed variation in the functional properties of the thin films with increasing thickness values.
