Abstract
Fe(100) films and wedge-shaped overlayers were grown epitaxially onto Ag(100) and investigated in situ by means of the surface magneto-optic Kerr effect. The reversible spin reorientation transition between perpendicular and in-plane alignment at , which is below the Curie temperature , is characterized for critical thicknesses along the length of a wedge. A similar asymmetry is identified within pseudogap regions in the vicinity of both and in which the remanent magnetization is small but nonvanishing.
