摘要：

The correlation between growth and magnetic anisotropy of thin Fe films deposited on ultra thin iron silicide template grown on Si(111) is investigated by means of scanning tunnelling microscopy and magneto optical Kerr effect experiments. The morphology of the film strongly depends on the Fe beam orientation relative to the sample normal. Whereas the Fe clusters are randomly distributed at normal incidence, oblique evaporation leads to the formation of elongated Fe islands perpendicular to the Fe beam. These distinct growth modes lead to drastically different magnetic anisotropies. An in-plane six-fold anisotropy magnetic easy axis has been evidenced for films deposited at normal incidence. The films evaporated at oblique incidence show an uniaxial in-plane magnetic easy axis parallel to the Fe stripes. This uniaxial anisotropy originates from long-ranged dipolar interactions.
