"Origin of the magnetic reorientation transition in Fe/Cu₃Au(001)";
Physical Review B, 69 (2004), S. 224408-1 - 224408-5.

The origin of the magnetic reorientation transition in ultrathin Fe films on Cu3Aus001d is investigated in
terms of ab-initio calculations of the magnetic anisotropy energy of the system. We find that this reorientation
transition is mainly determined by two factors, namely (1) segregation of Au into the Fe film, and (2) relaxation
of the interlayer distances with respect to the semi-infinite substrate, whereby the balance between these two
effects crucially depends on the thickness of the Fe slab.
