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 micromagnetic 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.
