The surface magneto-optic Kerr effect has been used to study the magnetic properties of fcc Fe stabilized by epitaxial growth on Cu(100). The studies are performed in ultra-high vacuum with auxiliary low-energy electron diffraction and Auger electron spectroscopy characterizations of the monolayer-range films and their growth. Two states have been observed for the Fe: a metastable, ferromagnetic state for the surface layer when the Fe is grown and held at elevated temperatures, and a stable, paramagnetic state both for Fe grown near room temperature and upon cooling a ferromagnetic film. Models to explain this unusual behavior are discussed.
