Static magnetization direction in fcc (111) Fe/Ni multilayers

The rotation of the static magnetization was measured by Mossbauer spectroscopy as 2.5 monolayers of resonating 57 Fe were moved from inside the Fe films to the Fe/Ni interfaces in Fe/Ni (17/200 A) multilayers produced by thermal evaporation. The results indicate a remarkable dependence of the tilt angle as a function of distance from the surface.
