Abstract—The possibility of controlling the magnetic anisotropy of multilayer [Fe/Pt]n structures grown by
magnetron sputtering of Fe and Pt plates by varying number n of layers is studied. Mössbauer spectroscopy data
and measured magnetic hysteresis loops demonstrate that the multilayer [Fe/Pt]n structures at n = 16 have a
predominantly perpendicular magnetic anisotropy. The results of X-ray photoelectron spectroscopy and micro-
magnetic simulation point to the presence of intermediate layers enriched in iron ions in the structures. The
magnetic anisotropy perpendicular to the surface of the [Fe/Pt]n films at n = 16 is found to be caused by the
anisotropy of the intermediate layers.
