Abstract

The direction of the spontaneous magnetization changes from out of plane to in plane at around x = 0.6 in [Ag(2.6 nm)/Fe(x nm)]~10~ multilayers (0.2 ≤ x ≤ 1) prepared on Si(111) substrate by vacuum evaporation. Transmission Mössbauer spectroscopy measurements of removed samples with a thick capping layer are compared to conversion electron Mössbauer spectroscopy measurements of samples on the Si substrate with a thin capping layer. The stress arising because of the application of a thick capping layer and the removal of the samples from the substrate is shown to have negligible effect on the spontaneous magnetization. The results support that the appearance of the perpendicular anisotropy below x = 0.6 is an intrinsic property of Fe/Ag multilayers. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
