摘要
We have studied the evolution of the magnetic in-plane anisotropy in epitaxial Fe/GaAs films for both (001) and ((1) over bar 10) orientations as a function of the Fe layer thickness using the in-situ longitudinal magneto-optic Kerr effect and ex-situ Brillouin light scattering. Magnetisation curves recorded during film growth reveal a continuous directional change of the anisotropy axes with increasing film thickness. This behaviour arises from the combination of a uniaxial and a cubic in-plane magnetic anisotropy which are both thickness dependent. We discuss the possible origins for this behaviour considering the substrate preparation and the structure of the Fe films.
