摘要：

Magnetic step anisotropies result from changed local symmetries of step atoms in comparison with surface atoms. They are determined experimentally for the case of steps along [001) on Fe(110) surfaces by comparing the anisotropies of epitaxial Fe(110) films on W(110) with smooth surfaces and those with a high density of steps along [001], as tested by spot profile analysis LEED (SPA-LEED). Surplus anisotropy energies per step atoms are of the same order as anisotropy energies per surface atom. The experimental results are in surprisingly good agreement with predictions from an appropriate extension of Neel's phenomenological model of surface anisotropies to step anisotropies.
