Thickness dependence of the magnetic anisotropy of Fe layers separated by Al

Research output: Contribution to journalArticle

Abstract

Magnetic multilayers of 57Fe with nominal thickness, T nom, between 0.4 and 1.0 nm separated by 3.0 nm Al spacer layers were prepared by alternate deposition of the constituents in high vacuum. The samples were investigated at 4.2 K in external magnetic field. A fraction of Fe atoms corresponding to about 0.3 nm equivalent Fe-thickness was found to mix into the Al spacer. The extremely strong magnetic anisotropy observed for T nomnom=0.8 nm, but full saturation was not achieved even for Tnom=1 nm and 3 T magnetic field applied perpendicularly to the sample plane.
