The spin reorientation transition (SRT) of ultrathin FeCo alloy films on an Au(111) surface and the magnetic/structural phase transition of epitaxial MnAs films on a GaAs(100) surface are studied by two electron microscopic techniques with very high surface sensitivity, i.e. spin‐polarized low‐energy electron microscopy (SPLEEM) and x‐ray magnetic circular dichroism photoemission electron microscopy (XMCDPEEM), combined with low‐energy electron microscopy (LEEM) and low‐energy electron diffraction (LEED), respectively. A new SRT mechanism is found and the interrelation between ferromagnetism and structure is elucidated. Copyright © 2005 John Wiley & Sons, Ltd.
