摘要：
Magnetic surface and interface anisotropies were determined for interfaces of Fe(110) with UHV, W, Cr, Cu, Ag and Au. This determination of single interface anisotropies is based on torsion oscillation magnetometry in situ in UHV of Fe(110)-films on Cr(110), in extension of previous work on Fe(110)-films on W(110). The out-of-plane anisotropy of the W(110)/ Fe(110) interface is easy plane with an extraordinary strength of 1.92 mJ/m(2), whereas all other interfaces show perpendicular out-of-plane anisotropy. The in-plane surface anisotropy supports [001] for Fe/Cr and Fe/Au interfaces, it supports [110] for W/Fe, Fe/UHV, Fe/Cu and Fe/Ag interfaces. Higher order terms of angular dependence beyond Neel's quadratic approximation are needed for a full description of magnetic surface anisotropies. A convenient notation is proposed.
